Description Ganesh 2026-09-17 07:00:34 UTC

Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

PCRE2 before 10.48 has a pcre2_match out-of-bounds read during the PCRE2_MATCH_INVALID_UTF matching of an invalid UTF subject.

Comment 1 Michel Lind 2026-10-06 14:52:38 UTC

This CVE is in a library this package links from the system and does not bundle; the fix ships in the library's own package and this package needs no change.
