CVE-2026-98375

The Linux kernel contains a vulnerability in the xen/netfront component where handle_incoming_queue() fails to verify if the pull_to length is at least ETH_HLEN . This allows a backend to provide a short RX slot, causing eth_type_trans() to either trigger a BUG() in __skb_pull() (if subsequent sl...

CVE-2026-98234

A flaw was found in the Linux kernel's Heavy-Hitter Filter HHF network packet scheduler. A local user with network administration privileges, such as within a container or user namespace, can set an excessively large flow limit due to missing upper-bound validation. When the system subsequently...

CVE-2026-98219

A flaw was found in the Linux kernel's schedext subsystem. A local attacker could exploit a race condition during scheduler initialization to cause a denial of service DoS or potentially escalate privileges. When an error is triggered during the enablement of an extensible scheduler, the kernel...

CVE-2026-98227

A flaw was found in the Linux kernel's MemoryStick block driver. The driver fails to release its internal input/output work queue when a card is removed from the system. A local attacker with physical access could exploit this flaw by repeatedly inserting and removing storage cards, gradually...

CVE-2026-98372

A flaw was found in the Linux kernel's IP Traffic Flow Security IP-TFS implementation within the XFRM subsystem. When processing incoming network traffic, a missing boundary check on packet fragment offsets allows an unbounded loop to read memory past the end of an on-stack array. A remote attack...

CVE-2026-98186

A flaw was found in the Linux kernel's mwifiex Wi-Fi driver. A nearby wireless attacker can exploit this vulnerability by broadcasting crafted Wi-Fi beacon or probe response frames containing an excessively large pairwise cipher count. Because the driver fails to validate this count against the...
