CVE-2024-26726

CVE-2024-26726 : In the Linux kernel, a Btrfs bug could panic when writing the free-space inode because the extent map was dropped on a write error and then looked up again, yielding EXTENT_MAP_HOLE on a second pass. The fix removes dropping the extent_map range for the failed free-space cache wr...

CVE-2024-26674

CVE-2024-26674 affects the Linux kernel x86/mm code, specifically a fixup path for get_user()/put_user(). In kernel builds >= 6.4 memory-error-injection can trigger a machine-check and panic due to a revert from _ASM_EXTABLE_UA() to a more generic fixup type. The issue arose when MCA handling ...
