However,\nbpf_jit_free() fails to free jit_data->ctx.offset, which causes a\nmemory leak of the JIT context offsets array.\n\nFix this by adding the missing kfree(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/riscv/net/bpf_jit_core.c"],"versions":[{"version":"48a8f78c50bd6f7f08fd40daa62252fd043f2f18","lessThan":"b594c23f584ab032a5eae809eee81b809dd27330","status":"affected","versionType":"git"},{"version":"48a8f78c50bd6f7f08fd40daa62252fd043f2f18","lessThan":"5cadc66b534fe8140441916200a20c7efb06a388","status":"affected","versionType":"git"},{"version":"48a8f78c50bd6f7f08fd40daa62252fd043f2f18","lessThan":"2a3a29e90021806ea00527f6458cfd2edb58b42a","status":"affected","versionType":"git"},{"version":"48a8f78c50bd6f7f08fd40daa62252fd043f2f18","lessThan":"369e4635d04801f394d5bd42556f21029e95ff93","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/riscv/net/bpf_jit_core.c"],"versions":[{"version":"6.6","status":"affected"},{"version":"0","lessThan":"6.6","status":"unaffected","versionType":"semver"},{"version":"6.12.110","lessThanOrEqual":"6.12.*","status":"unaffected","versionType":"semver"},{"version":"6.18.52","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"7.2.6","lessThanOrEqual":"7.2.*","status":"unaffected","versionType":"semver"},{"version":"7.3-rc1","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":"6.6","versionEndExcluding":"6.12.110"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.6","versionEndExcluding":"6.18.52"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.6","versionEndExcluding":"7.2.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.6","versionEndExcluding":"7.3-rc1"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/b594c23f584ab032a5eae809eee81b809dd27330"},{"url":"https://git.kernel.org/stable/c/5cadc66b534fe8140441916200a20c7efb06a388"},{"url":"https://git.kernel.org/stable/c/2a3a29e90021806ea00527f6458cfd2edb58b42a"},{"url":"https://git.kernel.org/stable/c/369e4635d04801f394d5bd42556f21029e95ff93"}],"title":"riscv, bpf: Fix memory leak in bpf_jit_free","x_generator":{"engine":"bippy-1.2.0"}}}}
