CVE-2026-72402

In the Linux kernel, the following vulnerability has been resolved: bpf: Mask pseudo pointer values in verifier logs printbpfinsn masks ldimm64 immediates for pointer-bearing pseudo sources when pointer leaks are not allowed, but the mask only covers BPFPSEUDOMAPFD and BPFPSEUDOMAPVALUE...

CVE-2026-72401

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix insnauxdata leak on verifier errfreeenv path When bpfcheck allocates env-insnauxdata successfully but later fails to allocate env-succ, it jumps directly to errfreeenv. The existing vfreeenv-insnauxdata sits before the...

CVE-2026-72111

In the Linux kernel, the following vulnerability has been resolved: bpf: Reset register bounds before narrowing retval range in checkmemaccess When the BPF verifier processes a context load of an LSM hook return value, it calls markregs32range to narrow the register to the hook's valid range...

CVE-2026-68462

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject negative const offsets for buffer pointers The verifier rejects variable offsets for PTRTOTPBUFFER and PTRTOBUF accesses, but it currently accepts a constant negative offset produced by pointer arithmetic. Commit...

EUVD-2026-59485

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject sleepable BPFLSMCGROUP programs at load time The cgroup shim runs under rcureadlockdontmigrate, so we should not attach any sleepable BPF programs there. Add support to the verifier to explicitly reject attempts to lo...

PT-2026-72611

In the Linux kernel, the following vulnerability has been resolved: bpf: Guard conntrack opts error writes The conntrack lookup and allocation kfuncs take an opts pointer together with an opts sz argument. The verifier checks only the memory range described by opts sz, but the wrappers...

CVE-2026-68295

A flaw was found in the Linux kernel. The LoongArch Just-In-Time JIT compiler for the Berkeley Packet Filter BPF subsystem incorrectly sign-extends the results of signed 32-bit division and modulo operations. This behavior causes the upper bits of BPF registers to be set, which differs from the...

CVE-2026-64353

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. This vulnerability occurs because the BPF verifier incorrectly handles dynamic inner array lookups in ARRAYOFMAPS. When an inner map template is replaced by a concrete inner array with a different maximum entry size, the...

CVE-2026-53081

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. This vulnerability occurs due to inconsistent base ID mapping when the regsafe function compares scalar registers with BPFADDCONST values. This inconsistency allows the BPF verifier to incorrectly succeed in state pruning...

CVE-2026-53090

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF verifier. When ldabs,ind instructions are used in BPF subprograms, the verifier fails to correctly simulate the abnormal exit path if packet data loading fails. This oversight could lead to unexpected behavior or bypass of security...
