However,\nbpf_jit_free() fails to free jit_data->ctx.offset, which causes a memory\nleak of the JIT context offsets array.\n\nSo fix this by adding the missing kvfree(jit_data->ctx.offset) in\nbpf_jit_free()."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["arch/loongarch/net/bpf_jit.c"],"versions":[{"version":"4ab17e762b34c847478f694932c4cd4b1ac2c343","lessThan":"f1557e0a64736b63aed24e285108a7bc3b7de294","status":"affected","versionType":"git"},{"version":"4ab17e762b34c847478f694932c4cd4b1ac2c343","lessThan":"47e20d4b3da97ef3881d1e55e43545c22424f3fc","status":"affected","versionType":"git"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["arch/loongarch/net/bpf_jit.c"],"versions":[{"version":"7.0","status":"affected"},{"version":"0","lessThan":"7.0","status":"unaffected","versionType":"semver"},{"version":"7.1.6","lessThanOrEqual":"7.1.*","status":"unaffected","versionType":"semver"},{"version":"7.2","lessThanOrEqual":"*","status":"unaffected","versionType":"original_commit_for_fix"}]}],"cpeApplicability":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"7.0","versionEndExcluding":"7.1.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"7.0","versionEndExcluding":"7.2"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/f1557e0a64736b63aed24e285108a7bc3b7de294"},{"url":"https://git.kernel.org/stable/c/47e20d4b3da97ef3881d1e55e43545c22424f3fc"}],"title":"LoongArch: BPF: Fix memory leak in bpf_jit_free()","x_generator":{"engine":"bippy-1.2.0"}}}}
