CVE-2024-27054: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: s390/dasd: fix double module refcount decrement Once the discipline is associated with the device, deleting the device takes care of decrementing the module's refcount. Doing it manually on this error path causes refcount to...

kernel: bpf: Make bpf_refcount_acquire fallible for non-owning refs

A memory-safety flaw was found in the Linux kernel extended Berkeley Packet Filter eBPF subsystem in the way reference counts are acquired for objects after a failed tree insertion. When a program attempts to acquire a reference to a node that may already have been released, the reference count...

kernel: hwmon: (coretemp) fix pci device refcount leak in nv1a_ram_new()

A counting logic flaw exists in the Linux kernel. When cigetdomainbusandslot is called, it returns a pci device with refcount incremented. When finishing it, the caller must decrement the reference count by calling pcidevput, leading to the loss of confidentiality of the system...

kernel: Linux kernel: Denial of Service due to memory leak in mlx5e driver

A flaw was found in the Linux kernel. This memory leak vulnerability occurs when a flow rule, forwarding packets from an internal port over a tunnel, is split and extra post-action rules are added. The intport object's reference count is incremented but never decremented, leading to the object no...
