CVE-2026-17507 MLS membership checks compare a uint32 leaf_index as signed, admitting an out-of-range sender

In Bouncy Castle for Java before 1.86, the MLS implementation org.bouncycastle.mls holds RFC 9420's uint32 leafindex in a signed int, so a wire value with the top bit set decodes to a negative number. That is a legitimate encoding rather than malformed input, and it must still decode, since the M...

Astra Linux – Vulnerability found in Linux 6.1, Linux 6.12

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...

Astra Linux – Vulnerability in glibc

There exists an exploitable signed comparison vulnerability in the ARMv7 memcpy implementation of GNU glibc 2.30.9000. Calling memcpy on ARMv7 targets that utilize the GNU glibc implementation with a negative value for the 'num' parameter results in a signed comparison vulnerability. If an attack...

Astra Linux – Vulnerability in libsoup2.4

The fix for CVE-2026-2443 was revised in a subsequent commit, where specific overflow checks were replaced with a general signed comparison. When a client sends a Range request with a suffix length exceeding the content size, the resulting negative start value is not properly clamped, resulting i...
