CVE-2025-8058 (GCVE-0-2025-8058)
Vulnerability from nvd
Published
2025-07-23 19:57
Modified
2025-11-04 21:15
Severity ?
5.9 (Medium) - CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:P/VC:L/VI:L/VA:H/SC:L/SI:L/SA:H
CWE
Summary
The regcomp function in the GNU C library version from 2.4 to 2.41 is subject to a double free if some previous allocation fails. It can be accomplished either by a malloc failure or by using an interposed malloc that injects random malloc failures. The double free can allow buffer manipulation depending of how the regex is constructed. This issue affects all architectures and ABIs supported by the GNU C library.

CVE-2025-5745 (GCVE-0-2025-5745)
Vulnerability from nvd
Published
2025-06-05 19:20
Modified
2025-06-05 20:13
Severity ?
5.6 (Medium) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:L/A:L
Summary
The strncmp implementation optimized for the Power10 processor in the GNU C Library version 2.40 and later writes to vector registers v20 to v31 without saving contents from the caller (those registers are defined as non-volatile registers by the powerpc64le ABI), resulting in overwriting of its contents and potentially altering control flow of the caller, or leaking the input strings to the function to other parts of the program.

CVE-2025-8058 (GCVE-0-2025-8058)
Vulnerability from cvelistv5
Published
2025-07-23 19:57
Modified
2025-11-04 21:15
Severity ?
5.9 (Medium) - CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:P/VC:L/VI:L/VA:H/SC:L/SI:L/SA:H
CWE
Summary
The regcomp function in the GNU C library version from 2.4 to 2.41 is subject to a double free if some previous allocation fails. It can be accomplished either by a malloc failure or by using an interposed malloc that injects random malloc failures. The double free can allow buffer manipulation depending of how the regex is constructed. This issue affects all architectures and ABIs supported by the GNU C library.
