CVE-2026-89762

CVE-2026-89762 is a Use-After-Free (UAF) vulnerability in the Linux kernel's AppArmor security module. The root cause lies in begin_current_label_crit_section(), which calls aa_replace_current_label() from LSM hooks to swap stale credentials. When the replacement occurs while a task has overridde...

In the Linux kernel, the following vulnerability has been resolved: apparmor: fix cred UAF caused by begincurrentlabelcritsection AppArmor's begincurrentlabelcritsection is a scary function called from lots of LSM hooks in particular VFS/socket-related ones that checks if the label referenced by...

CVE-2026-89760

CVE-2026-89760 is a Linux kernel vulnerability in the mm/swap subsystem where swap_free_hibernation_slot() incorrectly frees a hibernation slot while a folio still resides in the swap cache. When cluster readahead places a folio on a hibernation slot, freeing the slot clears the swap table entry ...

CVE-2026-89760

In the Linux kernel, the following vulnerability has been resolved: mm, swap: don't free a hibernation slot that is in the swap cache A slot with a folio in the swap cache is freed when the folio leaves the cache, not when its count drops. swapputentriescluster follows that rule...

CVE-2026-89750

CVE-2026-89750 is a Use-After-Free vulnerability in the Linux kernel's tracing/user_events subsystem. During fork, dup_task_struct() copies the user_event_mm pointer from the parent into the child without acquiring a reference. If user_event_mm_alloc() subsequently fails, the stale pointer is lef...
