CVE-2026-98027 net: dsa: mv88e6xxx: bound the policy rule dump by the caller's buffer size

In the Linux kernel, the following vulnerability has been resolved: net: dsa: mv88e6xxx: bound the policy rule dump by the caller's buffer size mv88e6xxxgetrxnfc uses rxnfc-rulecnt as the write index while dumping the policy IDR, clobbering the input value before it has been looked at. That input...

CVE-2026-97992

The Linux kernel contains a use-after-free vulnerability in the vhost-vdpa component. The issue occurs because vhost_vdpa_config_cb() accesses v->config_ctx without holding a lock or taking a reference, while VHOST_VDPA_SET_CONFIG_CALL replaces the field and immediately frees the old context v...

CVE-2026-97992 vhost-vdpa: protect config_ctx from being freed under the config callback

In the Linux kernel, the following vulnerability has been resolved: vhost-vdpa: protect configctx from being freed under the config callback vhostvdpaconfigcb loads v-configctx and signals it without taking a reference and without holding any lock: struct eventfdctx configctx = v-configctx; if...

CVE-2026-97983 vduse: return compat ioctl results directly

In the Linux kernel, the following vulnerability has been resolved: vduse: return compat ioctl results directly The compat handler handles VDUSEIOTLBGETFD and VDUSEVQGETINFO, but then calls the native handler. Their different command sizes make native dispatch return -ENOIOCTLCMD. For GETFD, this...

CVE-2026-97983

The Linux kernel contains a vulnerability in the vduse component where the compat handler incorrectly calls the native handler for VDUSE_IOTLB_GET_FD and VDUSE_VQ_GET_INFO commands. Because these commands have different sizes, the native dispatch returns -ENOIOCTLCMD, which overwrites the return ...

CVE-2026-97961

The Linux kernel contains a vulnerability in the perf/core subsystem where a list corruption can occur. The issue arises because the function perf_sched_cb_dec() may attempt to remove an entry from the sched_cb_list while that list node is still in use by perf_pmu_sched_task(). This specific path...

EUVD-2026-86815

In the Linux kernel, the following vulnerability has been resolved: perf/core: Allow listdel during perfeventoverflow A PMU might use perfschedcbinc and perfschedcbdec interface to get the PMU call back function pmu::schedtask invoked at schedule in and schedule out. This is achieved by walking...

CVE-2026-97604 fbdev: vfb: defer cleanup until the last reference

In the Linux kernel, the following vulnerability has been resolved: fbdev: vfb: defer cleanup until the last reference FBIOGETCMAP takes a shallow snapshot of info-cmap and performs the usercopy after dropping info-lock. vfbremove frees the colormap immediately after unregistering the framebuffer...

kernel: drm/virtio: use uninterruptible resv lock for plane updates

A flaw was found in the Linux kernel's VirtIO GPU Graphics Processing Unit driver. The virtiogpucursorplaneupdate and virtiogpuresourceflush functions fail to properly acquire a required lock, which can lead to a race condition. A local user could exploit this vulnerability by triggering a memory...
