kernel: wifi: mac80211: Fix deadlock in ieee80211_sta_ps_deliver_wakeup()

A vulnerability was found in the Linux kernel's mac80211 component within the ieee80211stapsdeliverwakeup function, where improper locking of the sta-pslock can lead to a deadlock condition, which occurs because the function uses a spin lock without preventing softirq execution on the same CPU,...

CVE-2024-46797 powerpc/qspinlock: Fix deadlock in MCS queue

In the Linux kernel, the following vulnerability has been resolved: powerpc/qspinlock: Fix deadlock in MCS queue If an interrupt occurs in queuedspinlockslowpath after we increment qnodesp-count and before node-lock is initialized, another CPU might see stale lock values in gettailqnode. If the...

CVE-2024-46797

CVE-2024-46797 : In the Linux kernel (PowerPC/MCS qspinlock), a deadlock can occur when an interrupt happens in queued_spin_lock_slowpath() after qnodesp->count is incremented but before node->lock is initialized. This can allow a CPU to see stale lock values and write the wrong qnode’s nex...

The vulnerability of the bpf component in the Linux operating system’s kernel allows a hacker to trigger a service failure.

The vulnerability of the bpf component in the Linux operating system’s kernel is related to a failure in bpfspinlock, when it is set as the value of bpftimer. This occurs because the bpfmapupdateelem call reassigns another timer object. Exploiting this vulnerability can allow an attacker to trigg...

SUSE CVE-2022-48940

In the Linux kernel, the following vulnerability has been resolved: bpf: Fix crash due to incorrect copymapvalue When both bpfspinlock and bpftimer are present in a BPF map value, copymapvalue needs to skirt both objects when copying a value into and out of the map. However, the current code does...
