CVE-2026-68295

CVE-2026-68295 covers the LoongArch Linux kernel BPF JIT: signed ALU32 div/mod results were not zero-extended, causing upper 32 bits to differ from the verifier/interpreter. The fix keeps sign-extension for operands (needed for signed division) but zero-extends the ALU32 result after divide/mod, ...

EUVD-2026-55396

In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Zero-extend signed ALU32 div/mod results ALU32 operations write a 32-bit result and leave the upper 32 bits of the BPF register zero. The LoongArch JIT sign-extends the result of signed ALU32 BPFDIV and BPFMOD...

Unity Linux 20.1070e Security Update: kernel (UTSA-2025-414582)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2025-414582 advisory. It was discovered that the eBPF implementation in the Linux kernel did not properly track bounds information for 32 bit registers when performing div and mod...

kernel: eBPF 32-bit source register truncation on div/mod

A flaw was found in the Linux kernel’s eBPF verification code, where the eBPF 32-bit div/mod source register truncation could lead to out-of-bounds reads and writes. By default, accessing the eBPF verifier is only possible to privileged users with CAPSYSADMIN. This flaw allows a local user who ca...

UBUNTU-CVE-2021-3600

It was discovered that the eBPF implementation in the Linux kernel did not properly track bounds information for 32 bit registers when performing div and mod operations. A local attacker could use this to possibly execute arbitrary code...
