CVE-2026-53069

A flaw was found in the Linux kernel's networking subsystem. This vulnerability, a null-pointer dereference, occurs in the XDP eXpress Data Path redirect mechanism when processing network traffic on a bonding device that has not been fully initialized. An attacker could potentially trigger this...

CVE-2026-52997

A flaw was found in the Linux kernel's schdualpi2 qdisc queueing discipline component. When dualpi2change attempts to enforce updated limit and memory limit values, it may incorrectly try to dequeue packets from an empty C-queue while packets are present in the L-queue. This can lead to a NULL sk...

CVE-2026-53032

A flaw was found in the Linux kernel's Berkeley Packet Filter BPF subsystem. This vulnerability occurs in the mapkptrmatchtype function when a scalar register is stored into a kernel pointer kptr slot. Due to an incorrect order of checks, the system attempts to access a null pointer, specifically...

CVE-2026-52991

A flaw was found in the Linux kernel's Pressure Stall Information PSI subsystem. A race condition exists between the file release and pressure write operations, specifically concerning the priv member of struct kernfsopenfile. This can lead to a use-after-free vulnerability or a NULL dereference,...
