8.8
CVSSv3
CVE-2022-42719
A use-after-free in the mac80211 stack when parsing a multi-BSSID element in the Linux kernel 5.2 up to and including 5.19.x prior to 5.19.16 could be used by attackers (able to inject WLAN frames) to crash the kernel and potentially execute code.

CVE-2021-3491
The io_uring subsystem in the Linux kernel allowed the MAX_RW_COUNT limit to be bypassed in the PROVIDE_BUFFERS operation, which led to negative values being usedin mem_rw when reading /proc/<PID>/mem. This could be used to create a heap overflow leading to arbitrary code e...

CVE-2022-42720
Various refcounting bugs in the multi-BSS handling in the mac80211 stack in the Linux kernel 5.1 up to and including 5.19.x prior to 5.19.16 could be used by local attackers (able to inject WLAN frames) to trigger use-after-free conditions to potentially execute code.

CVE-2022-20421
In binder_inc_ref_for_node of binder.c, there is a possible way to corrupt memory due to a use after free. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: An...

CVE-2022-3176
There exists a use-after-free in io_uring in the Linux kernel. Signalfd_poll() and binder_poll() use a waitqueue whose lifetime is the current task. It will send a POLLFREE notification to all waiters before the queue is freed. Unfortunately, the io_uring poll doesn't handle...

CVE-2021-4037
A vulnerability was found in the fs/inode.c:inode_init_owner() function logic of the LInux kernel that allows local users to create files for the XFS file-system with an unintended group ownership and with group execution and SGID permission bits set, in a scenario where a direct...

CVE-2021-3489
The eBPF RINGBUF bpf_ringbuf_reserve() function in the Linux kernel did not check that the allocated size was smaller than the ringbuf size, allowing an malicious user to perform out-of-bounds writes within the kernel and therefore, arbitrary code execution. This issue was fixed ...

CVE-2021-3490
The eBPF ALU32 bounds tracking for bitwise ops (AND, OR and XOR) in the Linux kernel did not properly update 32-bit bounds, which could be turned into out of bounds reads and writes in the Linux kernel and therefore, arbitrary code execution. This issue was fixed via commit 049c4...
