The vulnerability of the `sys_perf_event_open()` function in the Linux operating system’s perf subsystem allows a local attacker to gain root privileges.

The vulnerability of the sysperfeventopen function in the Linux operating system’s perf subsystem stems from the race condition within this subsystem. This condition can be exploited to initiate access to a freed memory area in the kernel. Exploiting this vulnerability allows a local attacker to...

The vulnerability of the ath9k_htc_wait_for_target function in the wireless adapter driver for Atheros in the Linux operating system allows a hacker to gain access to the kernel’s memory. This can lead to system failures or the leakage of internal kernel information.

The vulnerability of the ath9khtcwaitfortarget function in the wireless adapter driver for Atheros in Linux operating systems is related to an improper use after release. Exploiting this vulnerability can allow a perpetrator to gain access to kernel memory through the input of a specially created...
