| CVE-2022-50071 | 1 Linux | 1 Linux Kernel | 2025-11-17 | 7.8 High |
| In the Linux kernel, the following vulnerability has been resolved: mptcp: move subflow cleanup in mptcp_destroy_common() If the mptcp socket creation fails due to a CGROUP_INET_SOCK_CREATE eBPF program, the MPTCP protocol ends-up leaking all the subflows: the related cleanup happens in __mptcp_destroy_sock() that is not invoked in such code path. Address the issue moving the subflow sockets cleanup in the mptcp_destroy_common() helper, which is invoked in every msk cleanup path. Additionally get rid of the intermediate list_splice_init step, which is an unneeded relic from the past. The issue is present since before the reported root cause commit, but any attempt to backport the fix before that hash will require a complete rewrite. | ||||

| In the Linux kernel, the following vulnerability has been resolved: ASoC: ops: Consistently treat platform_max as control value This reverts commit 9bdd10d57a88 ("ASoC: ops: Shift tested values in snd_soc_put_volsw() by +min"), and makes some additional related updates. There are two ways the platform_max could be interpreted; the maximum register value, or the maximum value the control can be set to. The patch moved from treating the value as a control value to a register one. When the patch was applied it was technically correct as snd_soc_limit_volume() also used the register interpretation. However, even then most of the other usages treated platform_max as a control value, and snd_soc_limit_volume() has since been updated to also do so in commit fb9ad24485087 ("ASoC: ops: add correct range check for limiting volume"). That patch however, missed updating snd_soc_put_volsw() back to the control interpretation, and fixing snd_soc_info_volsw_range(). The control interpretation makes more sense as limiting is typically done from the machine driver, so it is appropriate to use the customer facing representation rather than the internal codec representation. Update all the code to consistently use this interpretation of platform_max. Finally, also add some comments to the soc_mixer_control struct to hopefully avoid further patches switching between the two approaches. | ||||

This also fixes a USBAN warning: UBSAN: invalid-load in ../sound/soc/fsl/imx-card.c:687:25 load of value 255 is not a valid value for type '_Bool' This is because playback_only is uninitialized and is not written to, as the playback-only property is absent. | ||||

Jason pointed out that "arm_smmu_impl_probe() has mis-ordered the devres callbacks if ops->device_remove() is going to be manually freeing things that probe allocated": https://lore.kernel.org/linux-iommu/20250407174408.GB1722458@nvidia.com/ In fact, tegra241_cmdqv_init_structures() only allocates memory resources which means any failure that it generates would be similar to -ENOMEM, so there is no point in having that "falling back to standard SMMU" routine, as the standard SMMU would likely fail to allocate memory too. Remove the unwind part in tegra241_cmdqv_init_structures(), and return a proper error code to ask SMMU driver to call tegra241_cmdqv_remove() via impl_ops->device_remove(). Then, drop tegra241_vintf_free_lvcmdq() since devres will take care of that. | ||||

| In the Linux kernel, the following vulnerability has been resolved: fs/eventpoll: fix endless busy loop after timeout has expired After commit 0a65bc27bd64 ("eventpoll: Set epoll timeout if it's in the future"), the following program would immediately enter a busy loop in the kernel: ``` int main() { int e = epoll_create1(0); struct epoll_event event = {.events = EPOLLIN}; epoll_ctl(e, EPOLL_CTL_ADD, 0, &event); const struct timespec timeout = {.tv_nsec = 1}; epoll_pwait2(e, &event, 1, &timeout, 0); } ``` This happens because the given (non-zero) timeout of 1 nanosecond usually expires before ep_poll() is entered and then ep_schedule_timeout() returns false, but `timed_out` is never set because the code line that sets it is skipped. This quickly turns into a soft lockup, RCU stalls and deadlocks, inflicting severe headaches to the whole system. When the timeout has expired, we don't need to schedule a hrtimer, but we should set the `timed_out` variable. Therefore, I suggest moving the ep_schedule_timeout() check into the `timed_out` expression instead of skipping it. brauner: Note that there was an earlier fix by Joe Damato in response to my bug report in [1]. | ||||

| In the Linux kernel, the following vulnerability has been resolved: arm64: cacheinfo: Fix incorrect assignment of signed error value to unsigned fw_level Though acpi_find_last_cache_level() always returned signed value and the document states it will return any errors caused by lack of a PPTT table, it never returned negative values before. Commit 0c80f9e165f8 ("ACPI: PPTT: Leave the table mapped for the runtime usage") however changed it by returning -ENOENT if no PPTT was found. The value returned from acpi_find_last_cache_level() is then assigned to unsigned fw_level. It will result in the number of cache leaves calculated incorrectly as a huge value which will then cause the following warning from __alloc_pages as the order would be great than MAX_ORDER because of incorrect and huge cache leaves value. | WARNING: CPU: 0 PID: 1 at mm/page_alloc.c:5407 __alloc_pages+0x74/0x314 | Modules linked in: | CPU: 0 PID: 1 Comm: swapper/0 Not tainted 5.19.0-10393-g7c2a8d3ac4c0 #73 | pstate: 20000005 (nzCv daif -PAN -UAO -TCO -DIT -SSBS BTYPE=--) | pc : __alloc_pages+0x74/0x314 | lr : alloc_pages+0xe8/0x318 | Call trace: | __alloc_pages+0x74/0x314 | alloc_pages+0xe8/0x318 | kmalloc_order_trace+0x68/0x1dc | __kmalloc+0x240/0x338 | detect_cache_attributes+0xe0/0x56c | update_siblings_masks+0x38/0x284 | store_cpu_topology+0x78/0x84 | smp_prepare_cpus+0x48/0x134 | kernel_init_freeable+0xc4/0x14c | kernel_init+0x2c/0x1b4 | ret_from_fork+0x10/0x20 Fix the same by changing fw_level to be signed integer and return the error from init_cache_level() early in case of error. | ||||

This makes rust currently incompatible with FineIBT. Add a Kconfig dependency that prevents FineIBT from getting turned on by default if rust is enabled. [ Rust 1.88.0 (scheduled for 2025-06-26) should have this fixed [1], and thus we relaxed the condition with Rust >= 1.88. When `objtool` lands checking for this with e.g. [2], the plan is to ideally run that in upstream Rust's CI to prevent regressions early [3], since we do not control `core`'s source code. Alice tested the Rust PR backported to an older compiler. Peter would like that Rust provides a stable `core` which can be pulled into the kernel: "Relying on that much out of tree code is 'unfortunate'". - Miguel ] [ Reduced splat. - Miguel ] | ||||

| In the Linux kernel, the following vulnerability has been resolved: drm/xe/vf: Perform early GT MMIO initialization to read GMDID VFs need to communicate with the GuC to obtain the GMDID value and existing GuC functions used for that assume that the GT has it's MMIO members already setup. However, due to recent refactoring the gt->mmio is initialized later, and any attempt by the VF to use xe_mmio_read|write() from GuC functions will lead to NPD crash due to unset MMIO register address: [] xe 0000:00:02.1: [drm] Running in SR-IOV VF mode [] xe 0000:00:02.1: [drm] GT0: sending H2G MMIO 0x5507 [] BUG: unable to handle page fault for address: 0000000000190240 Since we are already tweaking the id and type of the primary GT to mimic it's a Media GT before initializing the GuC communication, we can also call xe_gt_mmio_init() to perform early setup of the gt->mmio which will make those GuC functions work again. | ||||
