Red Hat has issued a security advisory for multiple vulnerabilities in the Linux kernel packages included in Red Hat Enterprise Linux 10. The update addresses several security flaws including use-after-free, improper resource handling, and validation issues across various kernel subsystems such as fsnotify, shmem, futex, drm/amd/display, ipc, mm/slab, and openvswitch. These vulnerabilities have been rated with an important security impact and affect Red Hat Enterprise Linux 10 and related CodeReady Linux Builder variants. A reboot is required after applying the update to ensure the fixes take effect.

In the Linux kernel, the following vulnerability has been resolved: shmem: fix recovery on rename failures maple_tree insertions can fail if we are seriously short on memory; simple_offset_rename() does not recover well if it runs into that. The same goes for simple_offset_rename_exchange(). Moreover, shmem_whiteout() expects that if it succeeds, the caller will progress to d_move(), i.e. that shmem_rename2() won't fail past the successful call of shmem_whiteout(). Not hard to fix, fortunately - mtree_store() can't fail if the index we are trying to store into is already present in the tree as a singleton. For simple_offset_rename_exchange() that's enough - we just need to be careful about the order of operations. For simple_offset_rename() solution is to preinsert the target into the tree for new_dir; the rest can be done without any potentially failing operations. That preinsertion has to be done in shmem_rename2() rather than in simple_offset_rename() itself - otherwise we'd need to deal with the possibility of failure after successful shmem_whiteout().
