{"id":"DEBIAN-CVE-2023-54045","details":"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.  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!
