CVE-2026-45972

The CVE-2026-45972 issue affects the Linux kernel SMB client, specifically smb2_open_file(), where improper handling could lead to memory corruption (UAF) or a double free during SMB2_open() retries. The fixed description states that zeroing err_iov and err_buftype before retrying SMB2_open() pre...

CVE-2026-45944

CVE-2026-45944 affects the Linux kernel IOMMU VT-d. During context-entry teardown, the implementation zeros a 128‑bit entry in two 64‑bit writes, risking a torn entry where the Present bit remains set while other fields are zeroed, potentially causing unpredictable behavior or spurious faults. Th...

CVE-2026-45892

CVE-2026-45892 affects the Linux kernel ext4 extent handling. The issue occurs when splitting an unwritten extent in the middle with EXT4_EXT_MAY_ZEROOUT and EXT4_EXT_DATA_VALID2, potentially leaving a stale unwritten extent in the extent status tree after maps are updated. The mitigation is a pa...
