kernel: bpf, sockmap: Prevent lock inversion deadlock in map delete elem

CVE-2024-35895 addresses a vulnerability in the Linux kernel's Berkeley Packet Filter BPF subsystem, specifically within the sockmap feature. The issue arises when BPF tracing programs, which can execute in various interrupt contexts, attempt to delete elements from sockmap or sockhash maps. This...

kernel: wifi: mt76: mt7921s: fix potential hung tasks during chip recovery

A vulnerability was found in the Linux kernel's mt76 driver for the mt7921s chip, where a potential deadlock could occur during chip recovery. This situation arises when the kernel worker resetwork holds a lock while waiting for the statworker thread, which is simultaneously waiting for the same...

kernel: pinctrl: fix deadlock in create_pinctrl() when handling -EPROBE_DEFER

A deadlock flaw was found in the Linux kernel’s pinctrl subsystem. This flaw allows a local user to crash the system...

kernel: nvmet-fc: avoid deadlock on delete association path

In the Linux kernel, the following vulnerability has been resolved: nvmet-fc: avoid deadlock on delete association path When deleting an association the shutdown path is deadlocking because we try to flush the nvmetwq nested. Avoid this by deadlock by deferring the put work into its own work item...

kernel: NFSv4: Don't hold the layoutget locks across multiple RPC calls

In the Linux kernel, the following vulnerability has been resolved: NFSv4: Don't hold the layoutget locks across multiple RPC calls When doing layoutget as part of the open compound, we have to be careful to release the layout locks before we can call any further RPC calls, such as setattr. The...

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,...
