- Summary
- CVE-2026-63381 affecting package mysql 8.0.46-1
- Details
-
Libevent is an event notification library. Prior to 2.1.13 and 2.2.2-alpha, libevent has a use-after-free in buffer.c when evbufferaddbufferreference processes an output buffer whose outtotallen is zero. evbufferfreeallchains frees the initial empty chain without resetting outbuf->first, outbuf->last, or outbuf->lastwithdatap, and APPENDCHAINMULTICAST subsequently dereferences the dangling chain pointer. A caller that can drive this buffer state can cause memory corruption or a process crash. This issue is fixed in versions 2.1.13 and 2.2.2-alpha.
