CVE-2025-68782
Estado: AplazadaAlta (7.5)—
In the Linux kernel, the following vulnerability has been resolved:
scsi: target: Reset t_task_cdb pointer in error case
If allocation of cmd->t_task_cdb fails, it remains NULL but is later dereferenced in the 'err' path.
In case of error, reset NULL t_task_cdb value to point at the default fixed-size buffer.
Found by Linux Verification Center (linuxtesting.org) with SVACE.
