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-2026-31526

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. When an exception occurs during the execution of a BPF subprogram, the system may fail to release user-acquired locks. This oversight can lead to resource leaks and system instability, potentially resulting in a Denial o...

CVE-2026-31525

CVE-2026-31525 concerns the Linux kernel BPF interpreter’s signed 32-bit division/modulo (sdiv32/smod32). The issue arises from using abs() on s32 operands, which is undefined for S32_MIN, causing incorrect results that can mismatch verifier behavior and enable out-of-bounds map access. A fix int...
