CVE-2026-16318 QUIC Transport Parameters Memory Leak During HelloRetryRequest in s2n-tls
The QUIC transport parameters extension handler in s2n-tls incorrectly uses s2nalloc instead of s2nrealloc to store the peer's transport parameters. When a TLS 1.3 connection goes through a HelloRetryRequest, the handler is called twice on the same connection. On the second call, s2nalloc zeroes...

In the Linux kernel, the following vulnerability has been resolved: tipc: fix double-free in tipcbufappend tipcmsgvalidate can potentially reallocate the skb it is validating, freeing the old one. In tipcbufappend, it was being called with a pointer to a local variable which was a copy of the...
GHSA-Q2GM-54R6-8FWM Oj: Use-After-Free in Oj::Parser SAJ Callback via Input Mutation
Summary Oj::Parserparse is vulnerable to a heap use-after-free when a SAJ/SAJ2 callback mutates the input JSON string during parsing. The C engine holds a raw const byte pointer into the Ruby string's internal buffer. If a callback e.g. hashstart resizes the string — for example by calling...

CVE-2026-41257
jq is a command-line JSON processor. In 1.8.1 and earlier, the jq bytecode VM's data stack tracks its allocation size in a signed int. When the stack grows beyond ≈1 GiB via deeply nested generator forks, the doubling arithmetic overflows. The wrapped value is passed to realloc and then used for ...
