In the Linux kernel, the following vulnerability has been resolved: usb: gadget: ffs: Remove WARNON from functionfsbind This commit addresses an issue related to a kernel panic that occurs when paniconwarn is enabled. The issue is caused by the unnecessary use of WARNON in functionfsbind, which c...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: KEYS: prevented NULL pointer dereference in findasymmetrickey. In findasymmetrickey, if all NULL values are passed as arguments to id0,1,2, the kernel will first emit a WARN message, but then there will be an oops because id2 wil...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.10, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: In the ftrace function, a potential warning was fixed in traceprintkseq during ftracedump. When ftracedumpone is called concurrently with reading from tracepipe, a WARNONONCE message can be triggered due to a race condition. The...

Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: drm/msm: Fixed the check on the return value of iommumapsgtable, and avoided issuing a WARN message. The commit “iommu: Return the full error code from iommumapsgatomic” changed iommumapsgtable to return an ssizet value, even in...

In the Linux kernel, the following vulnerabilities have been resolved: Bonding: Unnecessary warnings and logs from bondxdpgetxmitslave have been fixed. syzbot reported a warning in bondxdpgetxmitslave. To reproduce this issue1, one bonding device bond1 should have xdpdrv, which increases...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1, and Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: netfilter: xtIDLETIMER: Rejects the reuse of ALARM timer labels in revision 0 rules. In revision 0 rules, reusing timers by label always involves calling modtimer on the uninitialized timer-timer. If the label was created first i...

Astra Linux – Vulnerability found in Linux 5.15, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: staticcall: Replace the unnecessary WARNON call in staticcallmodulenotify. staticcallmodulenotify triggers a WARNON when memory allocation fails in staticcalladdmodule. This approach isn’t really justified, because the failure ca...

DEBIAN-CVE-2026-98061

In the Linux kernel, the following vulnerability has been resolved: bpf: Reject tail calls directly from callback frames A tail call from a non-zero frame is modeled as a return from that frame. The verifier makes R0 unknown and calls preparefuncexit for the taken branch. When the current frame i...

CVE-2026-98061

The Linux kernel contains a vulnerability in the BPF verifier where tail calls made directly from synchronous callback frames trigger a verifier bug. The root cause is that prepare_func_exit() marks register R0 as precise for callbacks, but the tail-call path synthesizes R0 instead of deriving it...
