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: xfs: Do not propagate ENODATA disk errors into the xattr code. ENODATA also known as ENOATTR has a very specific meaning in the xfs xattr code: it indicates that the requested attribute name could not be found. However, a medium...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bpf: Fixed an issue in verifying allowptrleaks. After we changed the capabilities of our networking-bpf program from capsysadmin to capnetadmin+capbpf, our networking-bpf program failed to start. This was because it failed the bp...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: TCP: TX zerocopy should not access the pfmemalloc status. We received a recent syzbot report 1 indicating a possible misuse of the page status in TCP zerocopy paths. Indeed, for pages originating from user space or other layers,...

CVE-2023-54181

CVE-2023-54181 concerns the Linux kernel BPF verifier: after migrating networking-bpf capabilities from cap_sys_admin to cap_net_admin+cap_bpf, the verifier incorrectly flagged a two-pointer comparison as a leak, blocking program startup. A patch fixes the allow_ptr_leaks check, addressing the fa...

CVE-2025-39835

In CVE-2025-39835, the Linux kernel XFS xattr code could leak ENODATA (ENOATTR) disk errors as a misleading “attribute not found,” potentially leading to an oops in xfs_attr_leaf_get() when a disk error returns ENODATA/ENOATTR with bp being NULL. The fix modifies lower IO error handling so disk e...
