OpenRISC signal handling has no network, adjacent-wireless, or physical-device entry point.\nAC:L - Exploitation is deterministic because the attacker fully controls the rt_sigframe SR field and can invoke rt_sigreturn directly; the fix author verified an unprivileged PoC on qemu-system-or1k that clears SPR_SR_DME and writes arbitrary physical memory.\nPR:L - Any unprivileged local process can call rt_sigreturn with a crafted sigframe on its own stack; the path performs only access_ok/copy_from_user checks and has no capability, authentication, or init-namespace root requirement.\nUI:N - No separate victim interaction is needed; the attacker can self-send a signal or directly syscall rt_sigreturn with a forged stack frame in their own process without requiring another user to mount, plug in, or approve anything.\nS:U - This is standard host-kernel privilege escalation by restoring attacker-controlled CPU privilege bits on sigreturn; it does not cross a VM guest/host, container sandbox, or IOMMU security boundary despite granting direct physical memory access.\nC:H - Clearing SPR_SR_DME disables data MMU translation and protection, allowing an unprivileged task to read arbitrary physical addresses including kernel memory; other exposed SR bits (SPR_SR_IME, SPR_SR_SUMRA, cache enables) further broaden privileged-state disclosure.\nI:H - With SPR_SR_DME cleared the CPU performs unprotected physical data accesses, giving arbitrary read/write to all of RAM; the fix commit PoC writes a marker beyond the kernel mem=32M reservation, demonstrating direct integrity compromise and local root escalation.\nA:H - Arbitrary physical memory writes can corrupt kernel text, data, or device MMIO and trigger oops or panic; manipulating privileged SR and cache-control bits can also destabilize the system even when full exploitation is not attempted."}]}], "affected": [{"product": "Linux", "vendor": "Linux", "defaultStatus": "unaffected", "repo": "https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git", "programFiles": ["arch/openrisc/include/asm/processor.h", "arch/openrisc/kernel/signal.c"], "versions": [{"version": "ac689eb7f9d4e270d1365853b82eece669387e2c", "lessThan": "bc2e24ba6e167ccf374a197457aa5640a802f429", "status": "affected", "versionType": "git"}, {"version": "ac689eb7f9d4e270d1365853b82eece669387e2c", "lessThan": "cf1b5514ddf9df098ce7e3741fc9679fd85a4ec6", "status": "affected", "versionType": "git"}, {"version": "ac689eb7f9d4e270d1365853b82eece669387e2c", "lessThan": "cd8b43a71755c516f5c1f265a103438ae9ab15be", "status": "affected", "versionType": "git"}, {"version": "ac689eb7f9d4e270d1365853b82eece669387e2c", "lessThan": "b4d73c3848bae9084fa8b9b2aa76d99a7d8eb17d", "status": "affected", "versionType": "git"}, {"version": "ac689eb7f9d4e270d1365853b82eece669387e2c", "lessThan": "89a91b30685c0493b0fa2b47d0ab41061a63069d", "status": "affected", "versionType": "git"}, {"version": "ac689eb7f9d4e270d1365853b82eece669387e2c", "lessThan": "a88d688be8d7f03cbf927f2ab454ea9fa58d2979", "status": "affected", "versionType": "git"}, {"version": "ac689eb7f9d4e270d1365853b82eece669387e2c", "lessThan": "212fc482ddd7f9ccdd74a05eab1cac849350dcd6", "status": "affected", "versionType": "git"}, {"version": "ac689eb7f9d4e270d1365853b82eece669387e2c", "lessThan": "32ef1b30ad736519f7a207bcc2986f3d4129d972", "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/openrisc/include/asm/processor.h", "arch/openrisc/kernel/signal.c"], "versions": [{"version": "3.1", "status": "affected"}, {"version": "0", "lessThan": "3.1", "status": "unaffected", "versionType": "semver"}, {"version": "5.10.266", "lessThanOrEqual": "5.10.*", "status": "unaffected", "versionType": "semver"}, {"version": "5.15.217", "lessThanOrEqual": "5.15.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.1.184", "lessThanOrEqual": "6.1.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.6.153", "lessThanOrEqual": "6.6.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.12.105", "lessThanOrEqual": "6.12.*", "status": "unaffected", "versionType": "semver"}, {"version": "6.18.46", "lessThanOrEqual": "6.18.*", "status": "unaffected", "versionType": "semver"}, {"version": "7.1.10", "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": "3.1", "versionEndExcluding": "5.10.266"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.1", "versionEndExcluding": "5.15.217"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.1", "versionEndExcluding": "6.1.184"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.1", "versionEndExcluding": "6.6.153"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.1", "versionEndExcluding": "6.12.105"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.1", "versionEndExcluding": "6.18.46"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.1", "versionEndExcluding": "7.1.10"}, {"vulnerable": true, "criteria": "cpe:2.3:o:linux:linux_kernel:*:*:*:*:*:*:*:*", "versionStartIncluding": "3.1", "versionEndExcluding": "7.2"}]}]}], "references": [{"url": "https://git.kernel.org/stable/c/bc2e24ba6e167ccf374a197457aa5640a802f429"}, {"url": "https://git.kernel.org/stable/c/cf1b5514ddf9df098ce7e3741fc9679fd85a4ec6"}, {"url": "https://git.kernel.org/stable/c/cd8b43a71755c516f5c1f265a103438ae9ab15be"}, {"url": "https://git.kernel.org/stable/c/b4d73c3848bae9084fa8b9b2aa76d99a7d8eb17d"}, {"url": "https://git.kernel.org/stable/c/89a91b30685c0493b0fa2b47d0ab41061a63069d"}, {"url": "https://git.kernel.org/stable/c/a88d688be8d7f03cbf927f2ab454ea9fa58d2979"}, {"url": "https://git.kernel.org/stable/c/212fc482ddd7f9ccdd74a05eab1cac849350dcd6"}, {"url": "https://git.kernel.org/stable/c/32ef1b30ad736519f7a207bcc2986f3d4129d972"}], "title": "openrisc: signal: do not restore privileged SR bits on sigreturn", "x_generator": {"engine": "bippy-1.2.0"}}}}
