| CVE-2025-68307 | 1 Linux | 1 Linux Kernel | 2025-12-18 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: can: gs_usb: gs_usb_xmit_callback(): fix handling of failed transmitted URBs The driver lacks the cleanup of failed transfers of URBs. This reduces the number of available URBs per error by 1. This leads to reduced performance and ultimately to a complete stop of the transmission. If the sending of a bulk URB fails do proper cleanup: - increase netdev stats - mark the echo_sbk as free - free the driver's context and do accounting - wake the send queue | ||||

| In the Linux kernel, the following vulnerability has been resolved: pinctrl: s32cc: fix uninitialized memory in s32_pinctrl_desc s32_pinctrl_desc is allocated with devm_kmalloc(), but not all of its fields are initialized. Notably, num_custom_params is used in pinconf_generic_parse_dt_config(), resulting in intermittent allocation errors, such as the following splat when probing i2c-imx: WARNING: CPU: 0 PID: 176 at mm/page_alloc.c:4795 __alloc_pages_noprof+0x290/0x300 [...] Hardware name: NXP S32G3 Reference Design Board 3 (S32G-VNP-RDB3) (DT) [...] Call trace: __alloc_pages_noprof+0x290/0x300 (P) ___kmalloc_large_node+0x84/0x168 __kmalloc_large_node_noprof+0x34/0x120 __kmalloc_noprof+0x2ac/0x378 pinconf_generic_parse_dt_config+0x68/0x1a0 s32_dt_node_to_map+0x104/0x248 dt_to_map_one_config+0x154/0x1d8 pinctrl_dt_to_map+0x12c/0x280 create_pinctrl+0x6c/0x270 pinctrl_get+0xc0/0x170 devm_pinctrl_get+0x50/0xa0 pinctrl_bind_pins+0x60/0x2a0 really_probe+0x60/0x3a0 [...] __platform_driver_register+0x2c/0x40 i2c_adap_imx_init+0x28/0xff8 [i2c_imx] [...] This results in later parse failures that can cause issues in dependent drivers: s32g-siul2-pinctrl 4009c240.pinctrl: /soc@0/pinctrl@4009c240/i2c0-pins/i2c0-grp0: could not parse node property s32g-siul2-pinctrl 4009c240.pinctrl: /soc@0/pinctrl@4009c240/i2c0-pins/i2c0-grp0: could not parse node property [...] pca953x 0-0022: failed writing register: -6 i2c i2c-0: IMX I2C adapter registered s32g-siul2-pinctrl 4009c240.pinctrl: /soc@0/pinctrl@4009c240/i2c2-pins/i2c2-grp0: could not parse node property s32g-siul2-pinctrl 4009c240.pinctrl: /soc@0/pinctrl@4009c240/i2c2-pins/i2c2-grp0: could not parse node property i2c i2c-1: IMX I2C adapter registered s32g-siul2-pinctrl 4009c240.pinctrl: /soc@0/pinctrl@4009c240/i2c4-pins/i2c4-grp0: could not parse node property s32g-siul2-pinctrl 4009c240.pinctrl: /soc@0/pinctrl@4009c240/i2c4-pins/i2c4-grp0: could not parse node property i2c i2c-2: IMX I2C adapter registered Fix this by initializing s32_pinctrl_desc with devm_kzalloc() instead of devm_kmalloc() in s32_pinctrl_probe(), which sets the previously uninitialized fields to zero. | ||||
| CVE-2025-68237 | 1 Linux | 1 Linux Kernel | 2025-12-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: mtdchar: fix integer overflow in read/write ioctls The "req.start" and "req.len" variables are u64 values that come from the user at the start of the function. We mask away the high 32 bits of "req.len" so that's capped at U32_MAX but the "req.start" variable can go up to U64_MAX which means that the addition can still integer overflow. Use check_add_overflow() to fix this bug. | ||||

| In the Linux kernel, the following vulnerability has been resolved: net: sxgbe: fix potential NULL dereference in sxgbe_rx() Currently, when skb is null, the driver prints an error and then dereferences skb on the next line. To fix this, let's add a 'break' after the error message to switch to sxgbe_rx_refill(), which is similar to the approach taken by the other drivers in this particular case, e.g. calxeda with xgmac_rx(). Found during a code review. | ||||

| In the Linux kernel, the following vulnerability has been resolved: platform/x86: intel: punit_ipc: fix memory corruption This passes the address of the pointer "&punit_ipcdev" when the intent was to pass the pointer itself "punit_ipcdev" (without the ampersand). This means that the: complete(&ipcdev->cmd_complete); in intel_punit_ioc() will write to a wrong memory address corrupting it. | ||||

| In the Linux kernel, the following vulnerability has been resolved: smb: client: fix incomplete backport in cfids_invalidation_worker() The previous commit bdb596ceb4b7 ("smb: client: fix potential UAF in smb2_close_cached_fid()") was an incomplete backport and missed one kref_put() call in cfids_invalidation_worker() that should have been converted to close_cached_dir(). | ||||
| CVE-2025-68319 | 1 Linux | 1 Linux Kernel | 2025-12-18 | 5.5 Medium |
| In the Linux kernel, the following vulnerability has been resolved: netconsole: Acquire su_mutex before navigating configs hierarchy There is a race between operations that iterate over the userdata cg_children list and concurrent add/remove of userdata items through configfs. The update_userdata() function iterates over the nt->userdata_group.cg_children list, and count_extradata_entries() also iterates over this same list to count nodes. Quoting from Documentation/filesystems/configfs.rst: > A subsystem can navigate the cg_children list and the ci_parent pointer > to see the tree created by the subsystem. This can race with configfs' > management of the hierarchy, so configfs uses the subsystem mutex to > protect modifications. Whenever a subsystem wants to navigate the > hierarchy, it must do so under the protection of the subsystem > mutex. Without proper locking, if a userdata item is added or removed concurrently while these functions are iterating, the list can be accessed in an inconsistent state. For example, the list_for_each() loop can reach a node that is being removed from the list by list_del_init() which sets the nodes' .next pointer to point to itself, so the loop will never end (or reach the WARN_ON_ONCE in update_userdata() ). Fix this by holding the configfs subsystem mutex (su_mutex) during all operations that iterate over cg_children. This includes: - userdatum_value_store() which calls update_userdata() to iterate over cg_children - All sysdata_*_enabled_store() functions which call count_extradata_entries() to iterate over cg_children The su_mutex must be acquired before dynamic_netconsole_mutex to avoid potential lock ordering issues, as configfs operations may already hold su_mutex when calling into our code. | ||||
| CVE-2025-68316 | 1 Linux | 1 Linux Kernel | 2025-12-18 | N/A |
| In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Fix invalid probe error return value After DME Link Startup, the error return value is set to the MIPI UniPro GenericErrorCode which can be 0 (SUCCESS) or 1 (FAILURE). Upon failure during driver probe, the error code 1 is propagated back to the driver probe function which must return a negative value to indicate an error, but 1 is not negative, so the probe is considered to be successful even though it failed. Subsequently, removing the driver results in an oops because it is not in a valid state. This happens because none of the callers of ufshcd_init() expect a non-negative error code. Fix the return value and documentation to match actual usage. | ||||

| In the Linux kernel, the following vulnerability has been resolved: hung_task: fix warnings caused by unaligned lock pointers The blocker tracking mechanism assumes that lock pointers are at least 4-byte aligned to use their lower bits for type encoding. However, as reported by Eero Tamminen, some architectures like m68k only guarantee 2-byte alignment of 32-bit values. This breaks the assumption and causes two related WARN_ON_ONCE checks to trigger. To fix this, the runtime checks are adjusted to silently ignore any lock that is not 4-byte aligned, effectively disabling the feature in such cases and avoiding the related warnings. Thanks to Geert Uytterhoeven for bisecting! | ||||

| In the Linux kernel, the following vulnerability has been resolved: vmw_balloon: indicate success when effectively deflating during migration When migrating a balloon page, we first deflate the old page to then inflate the new page. However, if inflating the new page succeeded, we effectively deflated the old page, reducing the balloon size. In that case, the migration actually worked: similar to migrating+ immediately deflating the new page. The old page will be freed back to the buddy. Right now, the core will leave the page be marked as isolated (as we returned an error). When later trying to putback that page, we will run into the WARN_ON_ONCE() in balloon_page_putback(). That handling was changed in commit 3544c4faccb8 ("mm/balloon_compaction: stop using __ClearPageMovable()"); before that change, we would have tolerated that way of handling it. To fix it, let's just return 0 in that case, making the core effectively just clear the "isolated" flag + freeing it back to the buddy as if the migration succeeded. Note that the new page will also get freed when the core puts the last reference. Note that this also makes it all be more consistent: we will no longer unisolate the page in the balloon driver while keeping it marked as being isolated in migration core. This was found by code inspection. | ||||

| In the Linux kernel, the following vulnerability has been resolved: posix-timers: Plug potential memory leak in do_timer_create() When posix timer creation is set to allocate a given timer ID and the access to the user space value faults, the function terminates without freeing the already allocated posix timer structure. Move the allocation after the user space access to cure that. [ tglx: Massaged change log ] | ||||

| In the Linux kernel, the following vulnerability has been resolved: net: netpoll: fix incorrect refcount handling causing incorrect cleanup commit efa95b01da18 ("netpoll: fix use after free") incorrectly ignored the refcount and prematurely set dev->npinfo to NULL during netpoll cleanup, leading to improper behavior and memory leaks. Scenario causing lack of proper cleanup: 1) A netpoll is associated with a NIC (e.g., eth0) and netdev->npinfo is allocated, and refcnt = 1 - Keep in mind that npinfo is shared among all netpoll instances. In this case, there is just one. 2) Another netpoll is also associated with the same NIC and npinfo->refcnt += 1. - Now dev->npinfo->refcnt = 2; - There is just one npinfo associated to the netdev. 3) When the first netpolls goes to clean up: - The first cleanup succeeds and clears np->dev->npinfo, ignoring refcnt. - It basically calls `RCU_INIT_POINTER(np->dev->npinfo, NULL);` - Set dev->npinfo = NULL, without proper cleanup - No ->ndo_netpoll_cleanup() is either called 4) Now the second target tries to clean up - The second cleanup fails because np->dev->npinfo is already NULL. * In this case, ops->ndo_netpoll_cleanup() was never called, and the skb pool is not cleaned as well (for the second netpoll instance) - This leaks npinfo and skbpool skbs, which is clearly reported by kmemleak. Revert commit efa95b01da18 ("netpoll: fix use after free") and adds clarifying comments emphasizing that npinfo cleanup should only happen once the refcount reaches zero, ensuring stable and correct netpoll behavior. | ||||

| In the Linux kernel, the following vulnerability has been resolved: NFS: Fix LTP test failures when timestamps are delegated The utimes01 and utime06 tests fail when delegated timestamps are enabled, specifically in subtests that modify the atime and mtime fields using the 'nobody' user ID. The problem can be reproduced as follow: # echo "/media *(rw,no_root_squash,sync)" >> /etc/exports # export -ra # mount -o rw,nfsvers=4.2 127.0.0.1:/media /tmpdir # cd /opt/ltp # ./runltp -d /tmpdir -s utimes01 # ./runltp -d /tmpdir -s utime06 This issue occurs because nfs_setattr does not verify the inode's UID against the caller's fsuid when delegated timestamps are permitted for the inode. This patch adds the UID check and if it does not match then the request is sent to the server for permission checking. | ||||

| In the Linux kernel, the following vulnerability has been resolved: nilfs2: avoid having an active sc_timer before freeing sci Because kthread_stop did not stop sc_task properly and returned -EINTR, the sc_timer was not properly closed, ultimately causing the problem [1] reported by syzbot when freeing sci due to the sc_timer not being closed. Because the thread sc_task main function nilfs_segctor_thread() returns 0 when it succeeds, when the return value of kthread_stop() is not 0 in nilfs_segctor_destroy(), we believe that it has not properly closed sc_timer. We use timer_shutdown_sync() to sync wait for sc_timer to shutdown, and set the value of sc_task to NULL under the protection of lock sc_state_lock, so as to avoid the issue caused by sc_timer not being properly shutdowned. [1] ODEBUG: free active (active state 0) object: 00000000dacb411a object type: timer_list hint: nilfs_construction_timeout Call trace: nilfs_segctor_destroy fs/nilfs2/segment.c:2811 [inline] nilfs_detach_log_writer+0x668/0x8cc fs/nilfs2/segment.c:2877 nilfs_put_super+0x4c/0x12c fs/nilfs2/super.c:509 | ||||
| CVE-2025-68239 | 1 Linux | 1 Linux Kernel | 2025-12-18 | 7.0 High |
| In the Linux kernel, the following vulnerability has been resolved: binfmt_misc: restore write access before closing files opened by open_exec() bm_register_write() opens an executable file using open_exec(), which internally calls do_open_execat() and denies write access on the file to avoid modification while it is being executed. However, when an error occurs, bm_register_write() closes the file using filp_close() directly. This does not restore the write permission, which may cause subsequent write operations on the same file to fail. Fix this by calling exe_file_allow_write_access() before filp_close() to restore the write permission properly. | ||||
