Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue is related to the debugfs feature in the Linux kernel, where a logic error in the wait/cancellation handling during remove operations can cause deadlocks. Specifically, when...

The vulnerability of the function ath11kdebugfs_remove_interface(), located in the driver drivers/net/wireless/ath/ath11k/debugfs.c of the wireless adapter ath11k driver for the Linux operating system, allows a hacker to cause a service failure.

The vulnerability of the function ath11kdebugfsremoveinterface in the drivers/net/wireless/ath/ath11k/debugfs.c file of the wireless adapter ath11k driver in the Linux kernel is related to the repeated release of previously released memory. Exploiting this vulnerability could allow an attacker to...

SUSE CVE-2022-48699

In the Linux kernel, the following vulnerability has been resolved: sched/debug: fix dentry leak in updatescheddomaindebugfs Kuyo reports that the pattern of using debugfsremovedebugfslookup leaks a dentry and with a hotplug stress test, the machine eventually runs out of memory. Fix this up by...

SUSE CVE-2022-48698

CVE-2022-48699

The CVE-2022-48699 issue affects the Linux kernel sched/debug path, where a dentry is leaked by using debugfs_remove(debugfs_lookup()) in update_sched_domain_debugfs. The root cause is improper dentry reference counting, which can, under hotplug stress, lead to memory exhaustion. The available fi...
