CVE-2026-64109 af_unix: Fix UAF read of tail->len in unix_stream_data_wait()

In the Linux kernel, the following vulnerability has been resolved: afunix: Fix UAF read of tail-len in unixstreamdatawait unixstreamdatawait does skbpeektail&sk-skreceivequeue without holding any lock that prevents SKBs on that queue from being dequeued and freed. This has been the case since...

CVE-2026-64021 drm/xe/oa: Fix exec_queue leak on width check in stream open

In the Linux kernel, the following vulnerability has been resolved: drm/xe/oa: Fix execqueue leak on width check in stream open In xeoastreamopenioctl, when param.execq-width 1 the function returns -EOPNOTSUPP directly, skipping the existing errexecq cleanup path. The execqueue reference obtained...

CVE-2026-64021

The CVE concerns the Linux kernel DRM subsystem (drm/xe/oa). The issue occurs in xe_oa_stream_open_ioctl() when param.exec_q->width > 1: it returns -EOPNOTSUPP directly, bypassing the err_exec_q cleanup path, causing a leaked reference from xe_exec_queue_lookup() and preventing the file’s p...

CVE-2026-64017

The CVE-2026-64017 issue affects the Linux kernel’s blk-mq path. A use-after-free could occur when submitting a bio to blk-mq if a cached request is peeked and then the code path decides to sleep before popping it; a plug flush would free cached_rqs via blk_mq_free_plug_rqs. The fix pops the cach...

CVE-2026-64012

The CVE affects the Linux kernel net/sched sch_sfb path. When sch_sfb has children (e.g., qfq) whose peek() callback is qdisc_peek_dequeued(), a dequeue on the parent can cause a NULL dereference in the child’s dequeue path, potentially leading to a kernel panic. The fix replaces the direct deque...
