Compensating controls
- Validate the affected product branch and deploy the verified fixed release.
- Restrict local access and enforce least privilege on affected hosts.
- Monitor vendor guidance and exploitation sources for a material change.
Verification
- Confirm that the asset runs Linux Linux and falls inside the recorded affected range.
- Verify the installed build against the product-specific fixed version after deployment.
- Validate exposure, authentication requirements and compensating controls in the actual environment.
- Reopen this reassessment when CVSS, KEV, EPSS, exploit evidence or remediation changes.
Remediation availability differs by product scope
Verified remediation exists for at least one product or source, but 160 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.
- Red Hat Product Security: 136 affected or under-investigation product states without a fixed product state in the same current advisory
- Siemens ProductCERT: 5 affected or under-investigation product states without a fixed product state in the same current advisory

Distribution package intelligence
23 package statesRelease-specific package status
Debian, ubuntu findings are scoped to the named distribution, release and source package. An absent finding does not mean a package is unaffected.
Package result overrides the generic status
BlackTree has verified remediation for at least one product or source, but the relevant distribution still reports no fixed package for 19 affected package states shown here. Treat those rows as affected with no fix until that distribution publishes a fixed version.
Repository candidate not checked
A published vendor fix does not prove that a matching update is enabled and installable on a particular asset. Confirm the local package candidate before scheduling remediation.

- Summary
- A flaw was found in the Linux kernel's Berkeley Packet Filter (BPF) verifier. A privileged local attacker can exploit an issue where the BPF verifier incorrectly handles memory initialization flags. This allows a BPF program to write to read-only memory maps, such as `.rodata` global maps, bypassing security checks. This could lead to unauthorized modification of kernel data or information disclosure.
- Remediation
- To mitigate this issue, ensure that unprivileged eBPF is disabled by setting `kernel.unprivileged_bpf_disabled` to 1. This prevents unprivileged users from loading eBPF programs. To check the current status, run: ```bash cat /proc/sys/kernel/unprivileged_bpf_disabled ``` If the output is 0, enable the mitigation by running: ```bash sudo sysctl -w kernel.unprivileged_bpf_disabled=1 ``` To make this change persistent across reboots, add or modify the following line in `/etc/sysctl.d/99-sysctl.conf` (or a similar sysctl configuration file): ``` kernel.unprivileged_bpf_disabled = 1 ``` Then, apply the changes: ```bash sudo sysctl --system ``` Note that these actions require root privileges.

- Summary
- In the Linux kernel, the following vulnerability has been resolved: bpf: Fix overloading of MEM_UNINIT's meaning Lonial reported an issue in the BPF verifier where check_mem_size_reg() has the following code: if (!tnum_is_const(reg->var_off)) /* For unprivileged variable accesses, disable raw * mode so that the program is required to * initialize all the memory that the helper could * just partially fill up. */ meta = NULL; This means that writes are not checked when the register containing the size of the passed buffer has not a fixed size. Through this bug, a BPF program can write to a map which is marked as read-only, for example, .rodata global maps. The problem is that MEM_UNINIT's initial meaning that "the passed buffer to the BPF helper does not need to be initialized" which was added back in commit 435faee1aae9 ("bpf, verifier: add ARG_PTR_TO_RAW_STACK type") got overloaded over time with "the passed buffer is being written to". The problem however is that checks such as the above which were added later via 06c1c049721a ("bpf: allow helpers access to variable memory") set meta to NULL in order force the user to always initialize the passed buffer to the helper. Due to the current double meaning of MEM_UNINIT, this bypasses verifier write checks to the memory (not boundary checks though) and only assumes the latter memory is read instead. Fix this by reverting MEM_UNINIT back to its original meaning, and having MEM_WRITE as an annotation to BPF helpers in order to then trigger the BPF verifier checks for writing to memory. Some notes: check_arg_pair_ok() ensures that for ARG_CONST_SIZE{,_OR_ZERO} we can access fn->arg_type[arg - 1] since it must contain a preceding ARG_PTR_TO_MEM. For check_mem_reg() the meta argument can be removed altogether since we do check both BPF_READ and BPF_WRITE. Same for the equivalent check_kfunc_mem_size_reg().
- Remediation
- Limit access to the interactive shell of the additional GNU/Linux subssytem to trusted personnel only.
High technical severity; prioritise exposed affected systems while verifying vendor guidance. Verified remediation exists for at least one product or source, but 160 structured product or package states remain unresolved. Apply remediation only to the exact product branch confirmed by its source.

Exploit reality and attack path
CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
Observed exploitation No confirmed evidence
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
Public PoC / exploit material None recorded
?
Confirmed exploitation and public exploit material are separate signals. Attacks can occur without public proof-of-concept or exploit code.No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.

- Action
- Use the product-specific evidence above. Patch only products with a verified fixed release, and keep every affected or under-investigation state without a matching fix in the remediation queue.
- Workaround
- To mitigate this issue, ensure that unprivileged eBPF is disabled by setting `kernel.unprivileged_bpf_disabled` to 1. This prevents unprivileged users from loading eBPF programs. To check the current status, run: ```bash cat /proc/sys/kernel/unprivileged_bpf_disabled ``` If the output is 0, enable the mitigation by running: ```bash sudo sysctl -w kernel.unprivileged_bpf_disabled=1 ``` To make this change persistent across reboots, add or modify the following line in `/etc/sysctl.d/99-sysctl.conf` (or a similar sysctl configuration file): ``` kernel.unprivileged_bpf_disabled = 1 ``` Then, apply the changes: ```bash sudo sysctl --system ``` Note that these actions require root privileges.
