Linux kernel 安全漏洞
The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel, which stems from incomplete live register markings in bpf, where the rX register is not marked as being used...
Linux kernel 安全漏洞
The Linux kernel is the kernel used by the Linux operating system developed by the Linux Foundation in the United States. There is a security vulnerability in the Linux kernel. This vulnerability stems from the checkmemaccess function in the BPF module, which matches PTRTOBUF pointers using...
PT-2026-38984
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the BPF subsystem where the check mem access function matches PTR TO BUF via base type, which strips PTR MAYBE NULL. This allows direct dereference of pointers without...
PT-2026-38972
Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the BPF verifier where live registers for indirect jumps are not properly marked. Specifically, for a gotox rX instruction, the rX register is not marked as used withi...
CVE-2026-43070
A flaw was found in the Linux kernel's BPF Berkeley Packet Filter verifier. The verifier fails to correctly reset a register's ID after a BPFEND byte swap operation. This oversight can lead to the verifier incorrectly propagating learned memory bounds to other registers, creating false confidence...
SUSE CVE-2026-43009
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix incorrect pruning due to atomic fetch precision tracking When backtrackinsn encounters a BPFSTX instruction with BPFATOMIC and BPFFETCH, the src register or r0 for BPFCMPXCHG also acts as a destination, thus receiving th...
CVE-2026-43070
In the Linux kernel, the following vulnerability has been resolved: bpf: Reset register ID for BPFEND value tracking When a register undergoes a BPFEND byte swap operation, its scalar value is mutated in-place. If this register previously shared a scalar ID with another register e.g., after an r1...
CVE-2026-43070
The CVE describes a Linux kernel BPF verifier flaw: after a BPF_END (byte swap), dst_reg->id is not reset to 0, which can cause the verifier to propagate learned bounds to a linked register, creating a risk of out-of-bounds memory accesses. The concrete impact is potential privilege/escalation...
CVE-2026-43030
A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. A logic error in the regsafe function, specifically when handling pointers to packets, could lead to an incorrect state where valid packet ranges are not properly explored. This vulnerability may allow an attacker to...
CVE-2026-43010
A flaw was found in the Linux kernel. A local user could attach a sleepable BPF kprobemulti program, which allows sleepable helper functions, such as bpfcopyfromuser, to be invoked from a non-sleepable context. This incorrect handling can lead to a system crash, resulting in a Denial of Service D...

CVE-2026-43030 bpf: Fix regsafe() for pointers to packet
In the Linux kernel, the following vulnerability has been resolved: bpf: Fix regsafe for pointers to packet In case rold-reg-range == BEYONDPKTEND && rcur-reg-range == N regsafe may return true which may lead to current state with valid packet range not being explored. Fix the bug...
