CVE-2026-78426 Logout bypass via alternate JWT spelling

The NeuVector JWT verifier accepts noncanonical Base64URL encodings of the same RSA signature field. An attacker holding a valid JWT that has not expired, but was logged out of NeuVector, can continue using the non-expired token with equivalent spelling of the RSA signature field until the token...

CVE-2026-78426: Incorrect Authorization

The NeuVector JWT verifier accepts noncanonical Base64URL encodings of the same RSA signature field. An attacker holding a valid JWT that has not expired, but was logged out of NeuVector, can continue using the non-expired token with equivalent spelling of the RSA signature field until the token...

CVE-2026-90217: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: bpf: Compare iterator types during state pruning An iterator stack slot can be MEMRCU or PTRUNTRUSTED. These states must not be equal, or the verifier can prune an unsafe path. Compare the pointer type for STACKITER slots...

SUSE CVE-2026-89706

In the Linux kernel, the following vulnerability has been resolved: nfsd: Reset write verifier when async COPY writeback fails Async COPY captures nn-writeverf at request time and reports it to the client via CBOFFLOAD after the worker kthread completes. When the post-copy vfsfsyncrange or...

CVE-2026-59638

A flaw was found in Bouncy Castle for Java. The Java Secure Socket Extension JSSE hostname verifier incorrectly enables the Common Name CN fallback by default, despite it being documented as an opt-in feature. This misconfiguration could allow a remote attacker to bypass proper hostname validatio...

Astra Linux – Vulnerability in Linux

The kernel/bpf/verifier.c file in the Linux kernel, as of version 5.12.1, performs undesirable speculative loads. This leads to the disclosure of stack contents through side-channel attacks, known as CID-801c6058d14a. The main issue is that the BPF stack area is not properly protected against...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: bpf: Skip invalid kfunc call in backtrackinsn The verifier skips invalid kfunc calls in checkkfunccall. Such calls would be caught by fixupkfunccall if they aren’t eliminated through dead code elimination. However, this can lead ...

Astra Linux – Vulnerability in Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: Tracing: Verify event formats that use "%p.." syntax. The trace event verifier checks the formats of trace events to ensure that they do not reference memory that is not part of the event itself, or data that will never be freed...

Astra Linux – Vulnerability found in Linux 5.10, Linux 6.1

In the Linux kernel, the following vulnerability has been resolved: bpf: Forgetting ranges when refining tnum after JSET Syzbot reported a kernel warning due to a range invariant violation in the following BPF program. 0: call bpfgetnetnscookie 1: if r0 == 0 goto 2: if r0 & Oxffffffff goto The...

Astra Linux – Vulnerability in Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: bpf, verifier: Fixed a memory leak in array reallocation for stack state. If an error NULL is returned by krealloc, callers of reallocarray would set their allocation pointers to NULL. However, when an error occurs in krealloc, i...

Astra Linux – Vulnerability in Linux, Linux 5.10

A flaw was discovered in the s390 eBPF JIT mechanism within bpfjitinsn in the arch/s390/net/bpfjitcomp.c file of the Linux kernel. In this flaw, a local attacker with special user privileges can bypass the verifier, potentially leading to confidentiality issues...
