This may\ncause a heap buffer overflow if the heap address is tagged because\nemit_a64_mov_i64() will emit longer code than it did during the size\ncalculation pass. The same problem could occur without tag-based\nKASAN if one of the 16-bit words of the stack address happened to\nbe all-ones during the size calculation pass. Fix the problem by\nassuming the worst case (4 instructions) when calculating the size\nof the bpf_tramp_image address emission."}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["arch/arm64/net/bpf_jit_comp.c"],"versions":[{"version":"077149478497b2f00ff4fd9da2c892defa6418d8","lessThan":"9e80f366ebfdfafc685fe83a84c34f7ef01cbe88","status":"affected","versionType":"git"},{"version":"d9664e6ff040798a46cdc5d401064f55b8676c83","lessThan":"f521c2a0c0c4585f36d912bf62c852b88682c4f2","status":"affected","versionType":"git"},{"version":"19d3c179a37730caf600a97fed3794feac2b197b","lessThan":"7db1a2121f3c7903b8e397392beec563c3d00950","status":"affected","versionType":"git"},{"version":"19d3c179a37730caf600a97fed3794feac2b197b","lessThan":"a552e2ef5fd1a6c78267cd4ec5a9b49aa11bbb1c","status":"affected","versionType":"git"},{"version":"6d218fcc707d6b2c3616b6cd24b948fd4825cfec","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/arm64/net/bpf_jit_comp.c"],"versions":[{"version":"6.11","status":"affected"},{"version":"0","lessThan":"6.11","status":"unaffected","versionType":"semver"},{"version":"6.11.6","lessThanOrEqual":"6.11.*","status":"unaffected","versionType":"semver"},{"version":"6.12","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":"6.11","versionEndExcluding":"6.11.6"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.11","versionEndExcluding":"6.12"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.10.3"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/9e80f366ebfdfafc685fe83a84c34f7ef01cbe88"},{"url":"https://git.kernel.org/stable/c/f521c2a0c0c4585f36d912bf62c852b88682c4f2"},{"url":"https://git.kernel.org/stable/c/7db1a2121f3c7903b8e397392beec563c3d00950"},{"url":"https://git.kernel.org/stable/c/a552e2ef5fd1a6c78267cd4ec5a9b49aa11bbb1c"}],"title":"bpf, arm64: Fix address emission with tag-based KASAN enabled","x_generator":{"engine":"bippy-1.2.0"}}}}
