Astra Linux – Vulnerability in Linux 5.10

In the Linux kernel, the following vulnerabilities have been resolved: gpio: wcd934x – Fixed the out-of-bounds shift error. The bit mask for pins 0 to 4 is actually BIT0 to BIT4, but we ended up using BITn – 1, which is incorrect. This issue was caught by the UBSAN check. UBSAN: Out-of-bounds shi...

The vulnerability in the driver module/gpio/gpio-wcd934x.c, a driver for supporting GPIO on the Linux operating system’s kernel, allows an attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability in the driver/gpio/gpio-wcd934x.c driver for Linux kernel’s GPIO support is related to an incorrect bit shifting of a integer value. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, and accessibility of the protected information...
