Name of the Vulnerable Software and Affected Versions Linux kernel versions through 5.19.12 Description The issue is related to a race condition in the Linux kernel, specifically in the drivers/char/pcmcia/synclink cs.c file. This condition can lead to a use-after-free scenario if a physically...

The vulnerability of the get_ctl_id_hash() function in the audio subsystem of Linux operating systems allows a hacker to increase their privileges or cause service failures.

The vulnerability of the getctlidhash function in the audio subsystem of Linux operating systems is related to reading data beyond the buffer boundaries in memory when processing the parameter id-name. Exploiting this vulnerability can allow an attacker to enhance their privileges or cause system...

Path traversal

The path in this case is a little bit convoluted. The end result is that via an ioctl an untrusted app can control the ui32PageIndex offset in the expression:sPA.uiAddr = pagetophyspsOSPageArrayData-pagearrayui32PageIndex;With the current PoC this crashes as an OOB read. However, given that the O...
