Astra Linux – Vulnerability in Linux, Linux 5.10

A use-after-free flaw was discovered in ncirequest in net/nfc/nci/core.c within the NFC Controller Interface NCI in the Linux kernel. This flaw could allow a local attacker with user privileges to cause a data race issue while the device is being removed, leading to a privilege escalation...

CVE-2026-43291

CVE-2026-43291 affects the Linux kernel NFC NCI subsystem. A parameter validation flaw for variable-length data packets can trigger a DoS by breaking NFC communication with NCI chips. Root cause: code compared variable-length packet data against a maximum length derived from sizeof(struct), ignor...
