glibc: glibc: Privilege escalation and arbitrary code execution via TOCTOU race condition in dynamic loader

A flaw was found in glibc, specifically within its dynamic loader ld.so. A local attacker can exploit a time-of-check to time-of-use TOCTOU race condition to escalate privileges and execute arbitrary code. This occurs when the dynamic loader expands $ORIGIN in DTRPATH for setuid/setgid programs,...

SUSE CVE-2026-86805

A time-of-check to time-of-use TOCTOU race condition in the dynamic loader ld.so of the GNU C Library glibc versions 2.14 through 2.44 allows a local attacker to escalate privileges. When expanding $ORIGIN in DTRPATH for setuid/setgid ATSECURE programs, glibc validates the lexically normalized...

SUSE CVE-2026-95818

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 ATSECURE programs. When such a program's DTRPATH or DTRUNPATH begins with $ORIGIN and is followed by NUL or '/' t...
