CVE-2026-45963

A flaw was found in the Linux kernel's ASoC nau8821 driver. This vulnerability occurs when the driver is unloaded, and a pending jack detection work jdetwork is not properly cancelled or allowed to complete. An attacker could exploit this by triggering the driver unload under specific conditions,...

CVE-2026-45965

A flaw was found in the AppArmor security module of the Linux kernel. When the exportbinary parameter is disabled at runtime, a previously loaded profile that is subsequently replaced can lead to a NULL pointer dereference. This occurs when the system attempts to resolve symbolic links to raw dat...

CVE-2026-45839

A flaw was found in the Linux kernel's BPF Berkeley Packet Filter CO-RE Compile Once - Run Everywhere accessor parsing. A local attacker with CAPBPF capabilities could craft a malicious BPF program that uses negative CO-RE accessor indices. This input validation vulnerability allows for an...

CVE-2026-45968 cpuidle: Skip governor when only one idle state is available

In the Linux kernel, the following vulnerability has been resolved: cpuidle: Skip governor when only one idle state is available On certain platforms PowerNV systems without a power-mgt DT node, cpuidle may register only a single idle state. In cases where that single state is a polling state sta...

CVE-2026-45963

CVE-2026-45963 affects the Linux kernel ASoC nau8821 driver. The issue occurs when unloading the driver while a jack-detection work (jdet_work) remains pending, which can crash the kernel if the work is scheduled. Root and OSV entries indicate patches were applied to fix Cancel delayed work on co...
