Astra Linux – Vulnerability in Linux 5.10
The checkaluop function in kernel/bpf/verifier.c in the Linux kernel, as of v5.16-rc5, did not properly update the bounds when handling the mov32 instruction. This issue allows local users to obtain potentially sensitive address information, also known as a “pointer leak.”...
Astra Linux – Vulnerability in Linux 6.1
In the Linux kernel, the following vulnerabilities have been resolved: bpf: Fixed the overloading of the meaning of MEMUNINIT Lonial reported an issue with the BPF verifier, where the checkmemsizereg function contains the following code: c if !tnumisconstreg-varoff / For unprivileged variable...
SUSE CVE-2026-98044
In the Linux kernel, the following vulnerability has been resolved: bpf: Reject legacy packet loads from callbacks checkldabs models a failed BPFLDABS or BPFLDIND in a subprogram as an implicit return with R0 set to zero. It calls preparefuncexit to explore this synthesized path. When the load is...

DEBIAN-CVE-2026-98084
In the Linux kernel, the following vulnerability has been resolved: bpf: backtracking shouldn't clear outer frame R1-R5 for callbacks When processing calls to bpfloop verifier marks R1 and R4 as precise. R1 tracks loop iterations number and because of the 'callbackdepth R1' mechanics in...
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-2026-98044
The Linux kernel contains a vulnerability in the BPF verifier where legacy packet-load instructions (BPF_LD_ABS or BPF_LD_IND ) used within synchronous callbacks trigger a "callback unexpected regs" verifier bug. Because check_ld_abs() models failed loads as implicit returns with R0 set to zero, ...
