CVE-2023-54045
Estado: AplazadaSin puntuar—
In the Linux kernel, the following vulnerability has been resolved:
audit: fix possible soft lockup in __audit_inode_child()
Tracefs or debugfs maybe cause hundreds to thousands of PATH records, too many PATH records maybe cause soft lockup.
Therefore, we add cond_resched() to __audit_inode_child() to fix it.
Detalles técnicos trazas, registros y código del informe original
For example: 1. CONFIG_KASAN=y && CONFIG_PREEMPTION=n 2. auditctl -a exit,always -S open -k key 3. sysctl -w kernel.watchdog_thresh=5 4. mkdir /sys/kernel/debug/tracing/instances/test There may be a soft lockup as follows: watchdog: BUG: soft lockup - CPU#45 stuck for 7s!
