there is no network exposure.\nAC:L - This is a race between the DRM scheduler running a queued job and the hwctx resource release, and the attacker controls both sides (submitting jobs and triggering destroy), so it can be reliably reproduced by looping create/submit/destroy cycles.\nPR:L - The relevant ioctls carry flag 0 with no capability or root check, and the NPU device is intended for unprivileged user-space ML applications, so any local user with device access can trigger it without elevated privileges.\nUI:N - The attacking process performs all steps (open, submit, destroy) itself; no victim action is required.\nS:U - The use-after-free corrupts kernel heap within the kernel's own security authority and does not cross into a separate VM/IOMMU boundary.\nC:H - The freed mailbox channel object can be reclaimed via heap spray, giving the attacker control over its contents and enabling kernel memory disclosure; per guidance UAF is High.\nI:H - The UAF on the channel object used for DMA/command submission enables heap-spray reallocation and controlled writes, providing an arbitrary-write/control-flow primitive.\nA:H - The race-induced use-after-free causes kernel oops/panic, as explicitly stated in the fix commit (\"use-after-free and crashes\")."}]}],"affected":[{"product":"Linux","vendor":"Linux","defaultStatus":"unaffected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/accel/amdxdna/aie2_ctx.c"],"versions":[{"version":"4fd6ca90fc7f509977585d39885f21b2911123f3","lessThan":"b79d31dce49b50c79620389b3639280802a86960","status":"affected","versionType":"git"},{"version":"4fd6ca90fc7f509977585d39885f21b2911123f3","lessThan":"688c3ff079b10e4600f040944430d3d4ff448a15","status":"affected","versionType":"git"},{"version":"4fd6ca90fc7f509977585d39885f21b2911123f3","lessThan":"f1370241fe8045702bc9d0812b996791f0500f1b","status":"affected","versionType":"git"},{"version":"36f781a3f0deac92f169416997a17e73538cf470","status":"affected","versionType":"git"},{"version":"6.14.9","lessThan":"6.15","status":"affected","versionType":"semver"}]},{"product":"Linux","vendor":"Linux","defaultStatus":"affected","repo":"https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git","programFiles":["drivers/accel/amdxdna/aie2_ctx.c"],"versions":[{"version":"6.15","status":"affected"},{"version":"0","lessThan":"6.15","status":"unaffected","versionType":"semver"},{"version":"6.18.14","lessThanOrEqual":"6.18.*","status":"unaffected","versionType":"semver"},{"version":"6.19.4","lessThanOrEqual":"6.19.*","status":"unaffected","versionType":"semver"},{"version":"7.0","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":"6.15","versionEndExcluding":"6.18.14"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.15","versionEndExcluding":"6.19.4"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.15","versionEndExcluding":"7.0"},{"vulnerable":true,"criteria":"cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*","versionStartIncluding":"6.14.9"}]}]}],"references":[{"url":"https://git.kernel.org/stable/c/b79d31dce49b50c79620389b3639280802a86960"},{"url":"https://git.kernel.org/stable/c/688c3ff079b10e4600f040944430d3d4ff448a15"},{"url":"https://git.kernel.org/stable/c/f1370241fe8045702bc9d0812b996791f0500f1b"}],"title":"accel/amdxdna: Stop job scheduling across aie2_release_resource()","x_generator":{"engine":"bippy-1.2.0"}}}}
