CVE-2026-98077

The Linux kernel contains an out-of-bounds (OOB) read vulnerability in the netfilter: nf_conntrack_sip component. The root cause is located in the sip_skip_whitespace() function, which fails to return NULL when its loop exhausts the buffer (where dptr == limit). Because the calling function ct_si...

kernel: drm/amdgpu/vcn3: Prevent OOB reads when parsing dec msg

A flaw was found in the Linux kernel's drm/amdgpu/vcn3 component. This vulnerability, an Out-of-Bounds OOB read, occurs when parsing decoder messages without proper boundary checks. A local attacker could potentially exploit this to read sensitive information from memory or cause system...
