curl: CVE-2026-92390: -J no-clobber guarantee bypassed with 103 early hints

Hi all, I found a way for a server to defeat --remote-header-name's -J no-clobber guarantee: with curl -O -J -i, sending a 103 Early Hints before the final response or an ETag ahead of Content-Disposition under --etag-save lets a server overwrite an existing file it names via Content-Disposition,...

CVE-2026-89723

A flaw was found in the nilfs2 file system component of the Linux kernel. When a file is truncated, an intermediate node block is not properly deleted and remains in the B-tree node cache. This can lead to the log writer incorrectly processing the block, resulting in a slab-out-of-bounds memory...

CVE-2026-89639

This vulnerability affects the Linux kernel's CIFS (Common Internet File System) implementation. When a file is opened with O_TRUNC , the function cifs_do_truncate() is invoked without holding i_rwsem, preventing it from performing a proper fscache cookie resize . As a result, stale cached data c...

curl: One Strict-Transport-Security response header empties the victim's entire HSTS store, silently,

Summary One Strict-Transport-Security response header, from any HTTPS server the victim contacts, leaves the victim's on-disk HSTS store at zero bytes. Every host in it loses HSTS protection, including hosts unrelated to the server that sent the header. curl exits 0 and prints nothing. Two...

kernel: NFSv4: include MAY_WRITE in open permission mask for O_TRUNC

A flaw was found in the Linux kernel's NFSv4 implementation. A local user could exploit a vulnerability where opening a file with OTRUNC truncate and ORDONLY read-only flags would bypass the necessary write permission checks. This oversight allows an attacker to truncate a file without having...

CVE-2026-56651: Improper Link Resolution Before File Access

Dool in versions up to 1.3.8 is vulnerable to symlink following when the "--devel" flag is used, as the application opens a log file without the "ONOFOLLOW" flag. A local attacker can exploit this by creating a symlink at the expected log file path pointing to a sensitive file, causing dool to...

CVE-2026-74596

A flaw was found in the Linux kernel's fsverity subsystem. The vulnerability is due to the removal of a check in the setattrprepare function, which previously verified if fs-verity was enabled. This change allows fsverity files to be truncated even when the fs-verity feature is not active on the...

CVE-2026-74592

A flaw was found in the Linux kernel's Integrity Measurement Architecture IMA. When a file is truncated, the system's integrity policy hooks are not properly instantiated, preventing the action cache flags from being reset. This oversight means that after truncation, the file is not re-collected,...
