CVE-2026-123158

sshd in OpenSSH before 10.6p2 on Linux, when musl libc is used without PAM, lacks a workaround for a password authentication bypass related to misinterpretation of whether a string is intended to be a password hash. For some configurations of accounts, any password between 256 and 1024 characters...

CVE-2026-107891

musl libc before 1.2.7, when an untrusted regular expression is used with regcomp, has multiple integer overflows, possibly leading to incorrect allocation sizes and out-of-bounds heap writes...

CVE-2026-6042-PoC

CVE-2026-6042: Algorithmic Complexity DoS in musl libc iconv Gap-skipping loops in musl's iconv GB18030 4-byte decoder allow a small crafted input to consume disproportionate CPU time. A 40 KB adversarial payload can pin a CPU core for over 40 minutes. Advisory :...

Astra Linux – vulnerability in musl

Musl libc up to version 1.1.23 contains an imbalance in the x87 floating-point stack adjustment, which is related to the math/i386/ directory. In some cases, using this library may result in out-of-bounds writes that are not present in the application’s source code...

Astra Linux – vulnerability in musl

In musl libc up to version 1.2.1, wcsnrtombs mishandles certain combinations of destination buffer size and source character limit, as evidenced by an invalid write access buffer overflow...

Astra Linux – Vulnerability in musl

Musl libc versions 0.9.13 through 1.2.5 before 1.2.6 have a out-of-bounds write vulnerability, which means that an attacker can trigger the iconv conversion of untrusted EUC-KR text to UTF-8...

Astra Linux – Vulnerability in musl

A security flaw has been discovered in musl libc up to version 1.2.6. The affected component is the iconv function in the src/locale/iconv.c file of the GB18030 4-byte Decoder component. Performing certain manipulations results in inefficient algorithmic complexity. The attack must be initiated...

Astra Linux – Vulnerability in musl

A issue was discovered in musl libc 0.7.10 through 1.2.6. Stack-based memory corruption can occur during the qsort function for very large arrays, due to incorrectly implemented double-word primitives. The number of elements must exceed about seven million, i.e., the 32nd Leonardo number on 32-bi...

CVE-2026-44453 h2o is vulnerable to musl libc stack overflow

h2o is an HTTP server with support for HTTP/1.x, HTTP/2 and HTTP/3. Prior to commit 6b5370d, h2o is vulnerable to a Denial of Service attack when calling alloca under certain conditions. When serving static files, h2o builds the file path on stack, by calling alloca. The maximum size of the memor...
