CVE-2024-38559

CVE-2024-38559: In the Linux kernel, the qedf SCSI path copies a userspace buffer without guaranteeing a NUL terminator, risking an OOB read in kstrtouint. The fix uses memdup_user_nul instead of memdup_user. Affected: kernel SCSI qedf path; Root cause: missing termination of the copied buffer. R...

CVE-2024-38559 scsi: qedf: Ensure the copied buf is NUL terminated

In the Linux kernel, the following vulnerability has been resolved: scsi: qedf: Ensure the copied buf is NUL terminated Currently, we allocate a count-sized kernel buffer and copy count from userspace to that buffer. Later, we use kstrtouint on this buffer but we don't ensure that the string is...
