CVE-2026-74731

A flaw was found in the Linux kernel's schedext component. A race condition can occur during the disabling of a sub-scheduler that was never properly linked into the scheduler hierarchy. This can lead to a use-after-free vulnerability, where exited tasks are re-homed onto a dying hierarchy. This...

CVE-2026-74724

A flaw was found in the Linux kernel's IPVS IP Virtual Server component. A local attacker can exploit this vulnerability by manipulating packets processed by IPVS, specifically within the ipvsnaticmp function. This manipulation can lead to an out-of-bounds write due to improper handling of the IP...

CVE-2026-74723

A flaw was found in the Linux kernel. A local attacker could craft a btrfs image with a malformed LZO compressed file extent. This could lead to an out-of-bounds read during decompression, potentially causing a denial of service...

kernel: rtmutex: Use waiter::task instead of current in remove_waiter()

A flaw was found in the Linux kernel. When the kernel's real-time mutex rtmutex component performs a specific operation called 'proxy-lock rollback' during futex requeue, it incorrectly handles task pointers. This can lead to a 'Use-After-Free' UAF vulnerability, where the system attempts to use...

kernel: gfs2: Fix use-after-free in iomap inline data write path

A flaw was found in the Linux kernel's GFS2 filesystem. This memory corruption vulnerability, a use-after-free, occurs in the iomap inline data write path. The issue arises because a data buffer is released prematurely while still being referenced, leading to a write to freed memory. This could...
