CVE-2026-64025

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter sockmap component when used with kernel TLS kTLS receive. A race condition exists where skpsockverdictdataready can improperly interact with the kTLS receive process. This can lead to a use-after-free vulnerability, potentially...

CVE-2026-63865

A flaw was found in the Linux kernel. The Berkeley Packet Filter BPF Linux Security Modules LSM feature incorrectly registered certain hooks, tasktoinode and inetconnestablished, as available for sleepable programs. These hooks are invoked in critical system contexts where program sleeping is not...

CVE-2026-63809

A flaw was found in the Linux kernel. An issue in the BPF Berkeley Packet Filter subsystem's sysctl handling can lead to memory corruption. Specifically, when a temporary buffer is allocated using kvzalloc but incorrectly freed with kfree, it can corrupt memory. A local attacker could exploit thi...

CVE-2026-64192 bpf: Reject BPF_MAP_TYPE_INODE_STORAGE creation if BPF LSM is uninitialized

However, if the BPF LSM is not explicitly enabled at...

CVE-2026-64192

CVE-2026-64192 affects the Linux kernel (BPF inode storage maps). When CONFIG_BPF_LSM=y and the BPF LSM is not enabled at boot, lsm_prepare() doesn’t run, so the BPF LSM blob size (lbs_inode) remains at the compiled default (8 bytes) instead of a larger offset. This lets a privileged user create/...
