CVE-2021-46910

A flaw was found in kmaplocal in the Linux Kernel that doubles the number of per-CPU fixmap slots allocated for kmaplocal. This causes the fixmap region to grow downwards beyond the start of its reserved window if the supported number of CPUs is large, eventually colliding with the newly added...

CVE-2021-46928

CVE-2021-46928 affects the Linux kernel on parisc: a trap7 (Instruction access rights) could leave the cr19 IIR register with a stale value. The patch fixes this by overwriting the stale IIR with the constant 0xbaadf00d when the trap occurs, preventing confusing dump values. The issue arises beca...
