Astra Linux - уязвимость в linux, linux-5.10

In the Linux kernel, the following vulnerabilities have been resolved: lib/fonts: Fixed undefined behavior in bit shifting for getdefaultfont. Shifting a signed 32-bit value by 31 bits is undefined; therefore, the significant bit was changed to unsigned. The UBSAN warning “calltrace” is as follow...

kernel: ext4: fix undefined behavior in bit shift for ext4_check_flag_values

A vulnerability was identified in the Linux kernel's ext4 filesystem implementation due to a flaw in how it processes filesystem metadata. An attacker with local privileges could create a malicious ext4 filesystem image to trigger this issue. When the system attempts to mount this malicious image...
