Astra Linux – Vulnerability in Linux, Linux 5.10

A flaw in the Linux kernel is found in the nfcmrvlnciunregisterdev function in the drivers/nfc/nfcmrvl/main.c file. This flaw can cause both read and write operations to be performed after the device has been freed, without synchronization between the cleanup routine and the firmware download...

Astra Linux – Vulnerability found in Linux 5.10, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: nfc: st-nci: Fixed a use-after-free bug in ndlcremove due to a race condition This bug affects both stncii2cremove and stncispiremove. Take stncii2cremove as an example. In stncii2cprobe, it calls ndlcprobe and binds &ndlc-smwork...

Astra Linux – Vulnerabilities in Linux, Linux-5.10, Linux-5.15, Linux-6.1

In the Linux kernel, the following vulnerability has been resolved: nfc: nci: fixed a possible NULL pointer dereferencing in sendacknowledge This issue involves handling memory allocation failures caused by nciskballoc, which calls allocskb. This fix prevents possible NULL pointer dereferences...

CVE-2026-43291

A flaw was found in the Linux kernel's Near Field Communication NFC NCI subsystem. Incorrect parameter validation for variable-length packet data can lead to communication failures with NCI NFC chips. This issue, stemming from an attempt to prevent access to uninitialized data, results in a Denia...
