CVE-2026-58051 libssh2 - Free of Uninitialized Pointer in publickey List Cleanup

libssh2 through 1.11.1 grows its publickey list with SSH2REALLOC but does not zero-initialize new entries before parsing populates them, so a parse failure reaching the cleanup path leaves libssh2publickeylistfree operating on an uninitialized entry. A malicious SSH server offering the publickey...

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...
