CVE-2024-41098

Kernel crash via unconditional ATA port cleanup

Published Jul 29, 2024 · Updated May 11, 2026

NULL pointer dereference in Linux kernel libata allows local users to crash the kernel when ATA host allocation fails. ata_host_release unconditionally accesses and frees ata_port members after ata_port_alloc returns an allocation failure, leaving those members uninitialized. Reaching the faulty cleanup path requires an ATA port allocation failure during host setup; the resulting page fault interrupts the entire system rather than only the initiating process.
