Astra Linux – vulnerability in linux-6.1

In the Linux kernel, the following vulnerability has been resolved: nfc: llcp: bound SNL TLV parsing to the skb and add length checks nfcllcprecvsnl walks through the SNL TLV list using a u16 offset/length pair derived from skb-len, without performing bounds checks on the actual skb data. Three...

Astra Linux – vulnerability in linux-6.1

In the Linux kernel, the following vulnerability has been resolved: nfc: llcp: read llcpsock-local under the socket lock in getsockopt nfcllcpgetsockopt reads llcpsock-local before locksocksk, then dereferences the cached pointer within the locked region. llcpsockbind assigns and clears...

Astra Linux – vulnerability in linux-6.1

In the Linux kernel, the following vulnerability has been resolved: nfc: llcp: avoid userspace overflow on invalid optlen nfcllcpgetsockopt casts optval to u32 user for putuser, so the kernel always stores 4 bytes regardless of the caller-supplied optlen. The existing mintu32, len, sizeofu32 only...

CVE-2026-98581

A flaw was found in the Linux kernel's Near Field Communication NFC Logical Link Control Protocol LLCP implementation. When handling specific disconnection packets, the kernel fails to properly lock and unlink sockets before updating their state, leading to internal socket list corruption. A loca...

CVE-2026-98580

A flaw was found in the Linux kernel's Near Field Communication NFC Logical Link Control Protocol LLCP implementation. A race condition occurs during concurrent socket release and connection accept operations due to improper lock synchronization. A local attacker could exploit this flaw to cause ...
