CVE-2022-49870

In CVE-2022-49870, the Linux kernel fixes undefined behavior in the CAP_TO_MASK bit-shift operation. The issue arises when shifting a signed 32-bit value by 31 bits, triggering UBSAN warnings (shift-out-of-bounds) reported in security/commoncap.c. The vulnerability stems from shifting a value tha...
