CVE-2026-92518

A flaw was found in the Linux kernel's RISC-V BPF JIT compiler. When Control-Flow Integrity CFI with Clang is enabled, an error in calculating the tail call jump offset can lead to kernel stack corruption. This issue causes the system to improperly adjust the stack pointer, which can result in...

CVE-2026-92518

In the Linux kernel, the following vulnerability has been resolved: riscv, bpf: Fix kernel stack corruption in tailcall with CFI When CONFIGCFICLANG is enabled, prog-bpffunc already skips the kcfi instruction during setup. Including it again in the tailcall jump offset causes it to jump over an...

CVE-2026-92519 riscv, bpf: Fix memory leak in bpf_jit_free

In the Linux kernel, the following vulnerability has been resolved: riscv, bpf: Fix memory leak in bpfjitfree When bpfintjitcompile is called for subprograms, it returns early during the first pass !prog-isfunc || extrapass is false, keeping ctx-offset alive for the subsequent extra pass. If JIT...

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description A memory leak occurs in the RISC-V BPF JIT compiler. When bpf int jit compile is called for subprograms, it may return early during the first pass, leaving ctx-offset active for a...

CVE-2021-47486

In the Linux kernel, the following vulnerability has been resolved: riscv, bpf: Fix potential NULL dereference The bpfjitbinaryfree function requires a non-NULL argument. When the RISC-V BPF JIT fails to converge in NRJITITERATIONS steps, jitdata-header will be NULL, which triggers a NULL...
