Astra Linux – Vulnerability in Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: CFI: Fixed the use of cfislowpathdiag with cpuidle. The use of RCUNONIDLE during cfislowpathdiag can result in an invalid RCU state in the cpuidle code path. WARNING: CPU: 1; PID: 0; at kernel/rcu/tree.c:613; rcueqsenter+0xe4/0x1...
Astra Linux – Vulnerability found in Linux 6.1, Linux 5.15
In the Linux kernel, the following vulnerability has been resolved: iouring/poll: A signed comparison in iopollgetownership was fixed. iopollgetownership uses a signed comparison to check whether pollrefs has reached the threshold for the slowpath: c if unlikelyatomicread&req-pollrefs =...
kernel: io_uring/poll: fix signed comparison in io_poll_get_ownership()
A flaw was found in the Linux kernel's iouring/poll component. A logic error exists in the iopollgetownership function due to an incorrect signed comparison. This flaw prevents the necessary slowpath from being triggered when the IOPOLLCANCELFLAG is set, potentially leading to unexpected behavior...

CVE-2026-52933
CVE-2026-52933 affects the Linux kernel’s io_uring/poll component. The root cause is a signed comparison in io_poll_get_ownership() where atomic_read(&req->poll_refs) is compared to IO_POLL_REF_BIAS; when IO_POLL_CANCEL_FLAG (BIT(31)) is set, the value becomes negative, causing the slowpath to...
