CVE-2026-45985 ext4: don't set EXT4_GET_BLOCKS_CONVERT when splitting before submitting I/O

In the Linux kernel, the following vulnerability has been resolved: ext4: don't set EXT4GETBLOCKSCONVERT when splitting before submitting I/O When allocating blocks during within-EOF DIO and writeback with dioreadnolock enabled, EXT4GETBLOCKSPREIO was set to split an existing large unwritten...

CVE-2026-45983 nfsd: never defer requests during idmap lookup

In the Linux kernel, the following vulnerability has been resolved: nfsd: never defer requests during idmap lookup During v4 request compound arg decoding, some ops e.g. SETATTR can trigger idmap lookup upcalls. When those upcall responses get delayed beyond the allowed time limit, cachecheck wil...

CVE-2026-45962 ublk: Validate SQE128 flag before accessing the cmd

In the Linux kernel, the following vulnerability has been resolved: ublk: Validate SQE128 flag before accessing the cmd ublkctrlcmddump accesses header sqe-cmd before IOURINGFSQE128 flag check. This could cause out of boundary memory access. Move the SQE128 flag check earlier in ublkctrluringcmd ...

CVE-2026-45962

The CVE affects the Linux kernel ublk driver, where ublk_ctrl_cmd_dump() could access (header *)sqe->cmd before checking IO_URING_F_SQE128, enabling out-of-bounds memory access. The mitigation is to check the SQE128 flag earlier in ublk_ctrl_uring_cmd() and return -EINVAL if not set. Several s...
