sed: GNU sed TOCTOU race condition

A Time-of-Check Time-of-Use TOCTOU race condition was found in GNU sed. When the -i in-place and --follow-symlinks options are used together, sed resolves the symlink but reopens the path for writing. An attacker with write access to the directory containing the symlink can swap it between the...

CVE-2026-31553

CVE-2026-31553 affects the Linux kernel KVM on arm64. The issue stems from computing descriptor addresses in __kvm_at_swap_desc() using (u64 __user )hva + offset, which miscomputes when offset ≠ 0, effectively performing offset 8. The correction is to use hva + offset to obtain the correct S1/S2 ...

GHSA-9GH9-HWPR-RVQQ uutils coreutils has a Time-of-Check to Time-of-Use (TOCTOU) race condition

A Time-of-Check to Time-of-Use TOCTOU race condition exists in the mkfifo utility of uutils coreutils. The utility creates a FIFO and then performs a path-based chmod to set permissions. A local attacker with write access to the parent directory can swap the newly created FIFO for a symbolic link...

uutils coreutils has a Time-of-check Time-of-use (TOCTOU) Race Condition

The touch utility in uutils coreutils is vulnerable to a Time-of-Check to Time-of-Use TOCTOU race condition during file creation. When the utility identifies a missing path, it later attempts creation using File::create, which internally uses OTRUNC. An attacker can exploit this window to create ...
