|---|---|---|---|---|---|---|---|
| CVE-2026-6238 | Med | 6.5 | < 0 | 0 | Apr 28, 2026 | The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.2 and newer fail to validate the RDATA content against the RDATA length in a DNS response when processing LOC, CERT, TKEY or TSIG records, which may allow an attacker to craft a DNS resp | |
| CVE-2026-5435 | Hig | 7.3 | < 0 | 0 | Apr 28, 2026 | The deprecated functions ns_printrrf, ns_printrr and fp_nquery in the GNU C Library version 2.2 and newer fail to enforce the caller-supplied buffer length, and can result in an out-of-bounds write when printing TSIG records. | |
| CVE-2026-5450 | Cri | 9.8 | < 2.43-r7 | 2.43-r7 | Apr 20, 2026 | Calling the scanf family of functions with a %mc (malloc'd character match) in the GNU C Library version 2.7 to version 2.43 with a format width specifier with an explicit width greater than 1024 could result in a one byte heap buffer overflow. | |
| CVE-2026-5358 | — | < 0 | 0 | Apr 20, 2026 | Rejected reason: REJECTED: CVE-2026-5358 is rejected for two reasons. Firstly it has been discovered that no NIS+ client or server was ever released for any Linux-based OS distributions and as such this makes the API provisional and unused. Secondly it has been discovered that t | ||
| CVE-2026-4046 | Hig | 7.5 | < 2.43-r6 | 2.43-r6 | Mar 30, 2026 | The iconv() function in the GNU C Library versions 2.43 and earlier may crash due to an assertion failure when converting inputs from the IBM1390 or IBM1399 character sets, which may be used to remotely crash an application. This vulnerability can be trivially mitigated by rem | |
| CVE-2026-4438 | Med | 5.4 | < 2.43-r4 | 2.43-r4 | Mar 20, 2026 | Calling gethostbyaddr or gethostbyaddr_r with a configured nsswitch.conf that specifies the library's DNS backend in the GNU C library version 2.34 to version 2.43 could result in an invalid DNS hostname being returned to the caller in violation of the DNS specification. | |
