In the Linux kernel, the following vulnerability has been resolved: ext4: drop extent cache after doing PARTIALVALID1 zeroout When splitting an unwritten extent in the middle and converting it to initialized in ext4splitextent with the EXT4EXTMAYZEROOUT and EXT4EXTDATAVALID2 flags set, it could...
CVE-2026-45858
CVE-2026-45858 affects the Linux kernel ext4 code. The issue occurs when allocating initialized blocks from a large unwritten extent or splitting an unwritten extent during end I/O, potentially leaving stale data if a split happens in the middle. The problem centers on ext4_split_extent() splitti...
