CVE-2026-45382

libde265 prior to v1.0.19 contains a heap-buffer-overflow read in decode_slice_unit_tiles caused by unvalidated PPS tile geometry (ctbAddrRS computed from PPS colBd/rowBd without ensuring it fits CtbAddrRStoTS.size() == sps->PicSizeInCtbsY). A malformed PPS that passes set_derived_values but e...

openssl: OpenSSL: Heap buffer overflow due to signed integer overflow in Unicode output sizing

A flaw was found in OpenSSL. A signed integer overflow vulnerability exists when sizing the destination buffer for Unicode output. This can lead to a heap buffer overflow, which may result in a crash or potentially allow an attacker to execute arbitrary code. Exploitation requires an application ...

CVE-2026-63881

A flaw was found in the Linux kernel's AMD KFD Kernel Fusion Driver debugger component. The getqueueids function, responsible for handling queue identifiers, contains an integer overflow vulnerability. This occurs when calculating the size of an array, where a malicious local user could provide a...
