Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerabilities have been resolved: drm/ttm: Fixed undefined behavior in bit shifting for TTMTTFLAGPRIVPOPULATED. Shifting a signed 32-bit value by 31 bits is undefined; therefore, the significant bit was changed to unsigned. The UBSAN warning appears as follows...

CVE-2022-50390

The CVE-2022-50390 issue is in the Linux kernel DRM TTM code. It fixes an undefined behavior when shifting a signed 32-bit value by 31 bits in TTM_TT_FLAG_PRIV_POPULATED, by changing the operation to unsigned to avoid UBSAN/shift-out-of-bounds warnings observed during framebuffer/VM operations. T...
