Summary
kernel security update
Details

The Linux Kernel, the operating system core itself.

Security Fix(es):

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: Android kernelAndroid ID: A-239630375References: Upstream kernel(CVE-2022-20421)

In emulation_proc_handler of armv8_deprecated.c, there is a possible way to corrupt memory due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is not needed for exploitation.Product: AndroidVersions: Android kernelAndroid ID: A-237540956References: Upstream kernel(CVE-2022-20422)

mm/rmap.c in the Linux kernel before 5.19.7 has a use-after-free related to leaf anon_vma double reuse.(CVE-2022-42703)

roccat_report_event in drivers/hid/hid-roccat.c in the Linux kernel through 5.19.12 has a race condition and resultant use-after-free in certain situations where a report is received while copying a report->value is in progress.(CVE-2022-41850)
