CVE-2026-43364

Summary (CVE-2026-43364) : In the Linux kernel ublk subsystem, a local attacker can trigger a NULL pointer dereference by sending UPDATE_SIZE to a ublk device that has been added but not started, or that has been stopped. The root cause is missing state validation in ublk_ctrl_set_size(), which d...
