Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLES12 / SLES15 / SLES_SAP15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2022:3362-1 advisory.

 - An issue was discovered in include/asm-generic/tlb.h in the Linux kernel before 5.19. Because of a race condition (unmap_mapping_range versus munmap), a device driver can free a page while it still has stale TLB entries. This only occurs in situations with VM_PFNMAP VMAs. (CVE-2022-39188)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel-livepatch-4_12_14-150000_150_92-default and / or kgraft-patch-4_12_14-95_108-default packages.
