GHSA-H6C4-MVXR-GF42
Vulnerability from github – Published: 2026-10-05 03:30 – Updated: 2026-10-05 12:31In Modem, there is a possible out of bounds read due to a missing permission check. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY01774038; Issue ID: MSV-8914.

Vulnerability from github – Published: 2026-10-09 15:31 – Updated: 2026-10-09 15:31The Affinity by Canva application before 3.3.1 (October 2026 release) did not correctly handle incomplete UTF-8 character sequences when parsing text in Affinity document files, leading to a heap buffer over-read. A threat actor could craft an Affinity document that, when opened by a user in Affinity, could disclose the contents of adjacent heap memory in the document's text or result in an application crash.

GHSA-H8WX-JCWQ-G3CP
Vulnerability from github – Published: 2026-04-28 21:36 – Updated: 2026-07-14 15:31The 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 response, causing a target application to crash or read uninitialized memory.
These functions are for application debugging only and hence not in the path of code executed by the DNS resolver. Further, they have been deprecated since version 2.34 and should not be used by any new applications. Applications should consider porting away from these interfaces since they may be removed in future versions.
