"value": "In the Linux kernel, the following vulnerability has been resolved:\n\napparmor: replace recursive profile removal with iterative approach\n\nThe profile removal code uses recursion when removing nested profiles,\nwhich can lead to kernel stack exhaustion and system crashes.\n\nReproducer:\n $ pf='a'; for ((i=0; i<1024; i++)); do\n echo -e \"profile $pf { \\n }\" | apparmor_parser -K -a;\n pf=\"$pf//x\";\n done\n $ echo -n a > /sys/kernel/security/apparmor/.remove\n\nReplace the recursive __aa_profile_list_release() approach with an\niterative approach in __remove_profile(). The function repeatedly\nfinds and removes leaf profiles until the entire subtree is removed,\nmaintaining the same removal semantic without recursion."
