BIT-PYTHON-MIN-2026-9669 bz2.BZ2Decompressor reuse after error can cause a stack buffer overflow

bz2.BZ2Decompressor objects could be reused after a decompression error. If an application caught the resulting OSError and retried with the same decompressor, crafted input could cause the decompressor to resume from an invalid internal state and perform out-of-bounds writes to a stack buffer...

CVE-2026-52995

The CVE-2026-52995 issue affects the Linux kernel’s RDS path: rds_for_each_conn_info() and rds_walk_conn_path_info() pass a caller-allocated on-stack buffer to visitors and then copy item_len bytes back to user space, potentially exposing uninitialized stack data. In particular, rds_ib_conn_info_...

GHSA-3M6Q-JJ5J-38C9 Oj: Stack Buffer Overflow in Oj::Doc#each_child via Deeply Nested Input

Summary Oj::Doceachchild, when invoked recursively over a deeply nested JSON document, overflows a fixed-size stack buffer and aborts the process. This is a denial of service reachable from untrusted JSON. Details Two-step chain in ext/oj/fast.c: 1. doceachchild line 1501 increments doc-where pas...

CVE-2026-48715

radvd is a router advertisement daemon for IPv6. Prior to version 2.21, the radvdump utility shipped with radvd contains a stack buffer overflow in the Route Information option parser. When processing a crafted ICMPv6 Router Advertisement, printff copies up to 2032 bytes from attacker-controlled...

Astra Linux – Vulnerability in faad2

A issue was discovered in faad2 through 2.10.0. A stack-buffer-overflow exists in the function ftypin located in mp4read.c. This allows an attacker to cause code execution...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Wifi: brwimac: pcie: handling of randbuf allocation failure The kzalloc function in brwimacpciedownloadfwnvram will return null if physical memory runs out. As a result, if we use getrandombytes to generate random bytes into the...

Astra Linux – Vulnerability in xwayland, xorg-server

A buffer overflow vulnerability was discovered in X.Org and Xwayland. The code in XkbVModMaskText allocates a fixed-sized buffer on the stack and copies the names of the virtual modifiers to that buffer. The code fails to check the bounds of the buffer and will copy the data regardless of the siz...

Astra Linux – Vulnerability in libde265

It was discovered that Libde265 v1.0.8 contains a stack-buffer-overflow vulnerability through the use of void putepelhvfallback in fallback-motion.cc. This vulnerability allows attackers to cause a Denial of Service DoS attack using a specially crafted video file...

Astra Linux – Vulnerability in gnutls28

A flaw was discovered in the GnuTLS library, specifically in the gnutlspkcs11tokeninit function, which handles PKCS11 token initialization. When a token label longer than expected is processed, the function writes beyond the end of a fixed-size stack buffer. This programming error can cause...

Astra Linux – Vulnerability in gst-plugins-base1.0

In GStreamer through 1.26.1, the subparse plugin’s parsesubriptime function may write data beyond the bounds of a stack buffer, resulting in a crash...
