Hi, The following vulnerability was published for glibc. CVE-2026-95818[0]: | A stack-based buffer overflow in the dynamic loader (ld.so) of the | GNU C Library (glibc) versions 2.14 through 2.44 allows a local | attacker to crash or corrupt the memory of setuid/setgid (AT_SECURE) | programs. When such a program's DT_RPATH or DT_RUNPATH begins with | $ORIGIN and is followed by NUL or '/' the loader both reads past the | end of the path buffer and writes past the end of a stack-allocated | internal buffer. The corrupted loader stack can lead to a loader | crash (denial of service) and limited disclosure of process memory. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
