CVE-2026-72402

CVE-2026-72402 : In the Linux kernel, the bpf verifier logs could reveal kernel pointer values via ldimm64 immediates for pointer-bearing pseudo sources. The function print_bpf_insn() previously masked only BPF_PSEUDO_MAP_FD and BPF_PSEUDO_MAP_VALUE; the risk extended to BPF_PSEUDO_MAP_IDX, BPF_P...

CVE-2026-72111 bpf: Reset register bounds before narrowing retval range in check_mem_access()

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-2026-72111

CVE-2026-72111 affects the Linux kernel BPF verifier. The issue occurs when processing a context load of an LSM hook return value: __mark_reg_s32_range() narrows the destination register by intersecting with stale bounds instead of replacing them, potentially creating a verifier/runtime mismatch ...

CVE-2026-68462

Summary of CVE-2026-68462 (Linux kernel, BPF): The issue arises in the verifier’s handling of buffer-pointer access (PTR_TO_TP_BUFFER and PTR_TO_BUF) where a constant negative offset could slip through after a pointer offset split (reg->var_off vs reg->off). Specifically, an access with reg...

PT-2026-72589

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A memory leak occurs in the BPF verifier when the bpf check function successfully allocates env-insn aux data but subsequently fails to allocate env-succ. In this scenario, the execution...

CVE-2026-74338: Undefined Security Weakness

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...
