Linux Kernel Security Vulnerabilities

The Linux kernel version 5.16 contains a security vulnerability. This vulnerability stems from the erofs LZMA decoder pool adjusting size during adjustment, failing to retain the old decoders after allocation. As a result, NULL values are passed to xzdecmicrolzmareset, potentially leading to null...

CVE-2026-98043: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: bpf: Don't infer non-NULL from a pointer with an unbounded offset regnotnull decides that a register holds a non-NULL value by looking at its type alone. For pointer types that allow arithmetic the type only guarantees a non-NULL...

CVE-2026-98145

In the Linux kernel, the following vulnerability has been resolved: accel/amdxdna: reject a command chain that carries no commands A chain whose commandcount is zero passes the payload length check, because structsizepayload, data, 0 is just the header. The fill loop then does not run, so offset...
