CVE-2022-50229

In the Linux kernel, the following vulnerability has been resolved: ALSA: bcd2000: Fix a UAF bug on the error path of probing When the driver fails in sndcardregister at probe time, it will free the 'bcd2k-midiouturb' before killing it, which may cause a UAF bug. The following log can reveal it:...

CVE-2022-50219

In CVE-2022-50219, the issue is in the Linux kernel’s BPF subsystem. Syzbot reported a use-after-free in compute_effective_progs when detaching BPF links, where a freed memory path could be dereferenced by update_effective_progs() leading to a KASAN UAF. The fix removes the pointer from the cgrou...

CVE-2022-50168

CVE-2022-50168 (Linux kernel) : A race/cleanup bug in BPF JIT on x86 allowed freeing of a not-finalized bpf_prog_pack, triggered when multiple subprogs are processed. The root cause was that jit_subprogs() could free subprograms before bpf_jit_binary_pack_finalize() had run for them, risking free...

CVE-2022-50164

CVE-2022-50164 concerns the Linux kernel wifi driver (iwlwifi, mvm). The issue is a bug in iwl_mvm_mac_wake_tx_queue where a double list_add can leave related lists uncleared after a successful station association if station queues are disabled, allowing a new element to link with a stale one. Th...
