What to do
AI-suggested
A fix for this vulnerability has been implemented in the Linux kernel. Users and administrators should apply the official kernel updates that address this off-by-one error in sd_read_block_characteristics(). Since this is a kernel-level flaw, patching the kernel is the recommended and effective mitigation. No alternative mitigations or workarounds are indicated.
Description
CVE-2024-47682 is a high-severity vulnerability in the Linux kernel's SCSI subsystem. It involves an off-by-one error in the function sd_read_block_characteristics(), which can lead to an out-of-bounds memory access when processing certain device responses, such as those from QEMU v2.x. This flaw could potentially allow an attacker with local privileges to cause memory corruption.
