SUSE CVE-2026-31525

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix undefined behavior in interpreter sdiv/smod for INTMIN The BPF interpreter's signed 32-bit division and modulo handlers use the kernel abs macro on s32 operands.

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...
