Описание
A use-after-free flaw was found in radix_tree_lookup in ./lib/radix-tree.c in the Radix tree node cache in the Linux Kernel. This issue could allow a local attacker to crash the system and could lead to a kernel information leak problem.
Отчет
The SRCU code was added in upstream kernel v6.4-rc1 and removed before v6.4. This bug only existed in development kernels. Please see https://lore.kernel.org/all/ZTKVfoQZplpB8rki@casper.infradead.org and https://bugzilla.suse.com/show_bug.cgi?id=1215932 for more information.
Меры по смягчению последствий
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
