This Red Hat security advisory addresses multiple vulnerabilities and bugs in the Linux kernel packages for Red Hat Enterprise Linux 10. The update includes fixes for seven CVEs affecting kernel components such as fsnotify, shmem, futex, AMD display DRM, IPC, slab memory management, and Open vSwitch networking. The advisory emphasizes the importance of applying the update and rebooting systems to ensure the fixes take effect. No CVSS scores are provided, but the overall severity is rated as important by Red Hat.

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().
