Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerabilities have been resolved: hwmon: tps53679 Fixed array access with zero-length block reads. i2csmbusreadblockdata can return 0, indicating a zero-length read. When this occurs, tps53679identifychip accesses bufret - 1, which is actually buf-1. This mean...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: iouring/rsrc: Rejects zero-length fixed buffer imports. The validatefixedrange function allows for the use of bufaddr at the exact end of the registered region when len is zero. This occurs because the check uses a strict...
Astra Linux – Vulnerability in Linux 5.10
In the Linux kernel, the following vulnerability has been resolved: i2c: rtl9300 – ensure that the data length is within the supported range. A explicit check for the transfer length should be added to ‘rtl9300i2cconfigxfer’ to ensure that the data length is not within the supported range. In...
dnsmasq: NSEC bitmap parsing infinite loop
A denial of service vulnerability was discovered in dnsmasq's DNSSEC validation. When parsing NSEC and NSEC3 bitmap records, the window iteration logic fails to account for the 2-byte window header when advancing through the bitmap data. A specially crafted DNS response with a zero-length bitmap...

CVE-2026-44699
LibJWT is a C JSON Web Token Library. From 3.0.0 to 3.3.2, libjwt accepts an RSA JWK that does not contain an alg parameter as the verification key for an HS256/HS384/HS512 token. In the OpenSSL backend, this causes HMAC verification to run with a zero-length key, so an attacker can forge a valid...

kernel: out-of-bound read in memcpy_fromiovecend()
A flaw was found in the Linux kernel that allows the userspace to call memcpyfromiovecend and similar functions with a zero offset and buffer length. This can cause a read beyond the buffer boundaries flaw and, in certain cases, cause a memory access fault and a system halt by accessing invalid...
