Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- In the Linux kernel, the following vulnerability has been resolved: LoongArch: BPF: Fix off-by-one error
in build_prologue() Vincent reported that running BPF progs with tailcalls on LoongArch causes kernel hard
lockup. Debugging the issues shows that the JITed image missing a jirl instruction at the end of the
epilogue. There are two passes in JIT compiling, the first pass set the flags and the second pass
generates JIT code based on those flags. With BPF progs mixing bpf2bpf and tailcalls, build_prologue()
generates N insns in the first pass and then generates N+1 insns in the second pass. This makes
epilogue_offset off by one and we will jump to some unexpected insn and cause lockup. Fix this by
inserting a nop insn. (CVE-2025-37893)
