kernel: netfilter: nf_conntrack_h323: check for zero length in DecodeQ931()
A flaw was found in the Linux kernel's netfilter subsystem, specifically within the nfconntrackh323 module. This vulnerability occurs in the DecodeQ931 function when processing a zero-length value from a packet. An integer underflow during a length calculation results in a large, incorrect value...

kernel: io_uring/rsrc: reject zero-length fixed buffer import
A flaw was found in the Linux kernel's iouring subsystem. A local attacker can exploit a vulnerability in the ioimportfixed function by importing a zero-length fixed buffer. This can lead to an out-of-bounds read from slab memory, potentially resulting in information disclosure or a denial of...

The kernel-rt packages provide the Real Time Linux Kernel, which enables fine-tuning for systems with extremely high determinism requirements. Security Fixes: kernel: Bluetooth: MGMT: Fix possible UAFs CVE-2025-39981 kernel: ima: don't clear IMADIGSIG flag when setting or removing non-IMA xattr...
JLSEC-2026-522
A NULL pointer dereference flaw was found in GnuTLS. As Nettle's hash update functions internally call memcpy, providing zero-length input may cause undefined behavior. This flaw leads to a denial of service after authentication in rare circumstances...
gnutls: GnuTLS: Denial of Service via DTLS zero-length fragment
A flaw in GnuTLS DTLS handshake parsing allows malformed fragments with zero length and non-zero offset, leading to an integer underflow during reassembly and resulting in an out-of-bounds read. This issue is remotely exploitable and may cause information disclosure or denial of service...
