NVD Description

Note: Versions mentioned in the description apply only to the upstream kernel-uek-debug-modules-extra package and not the kernel-uek-debug-modules-extra package as distributed by Oracle. See How to fix? for Oracle:10 relevant fixed versions and status.

In the Linux kernel, the following vulnerability has been resolved:

xfrm: validate selector family and prefixlen during match

syzbot reported a shift-out-of-bounds in xfrm_selector_match() due to AF_UNSPEC selector with large prefixlen (e.g. 128) matched against IPv4 flow (when XFRM_STATE_AF_UNSPEC is set).

Fix this by:

  • Rejecting mismatched families in xfrm_selector_match.
  • Returning false in addr4_match if prefixlen > 32.
  • Returning false in addr_match if prefixlen > 128 (prevents overflow).
