CVE-2022-50012 powerpc/64: Init jump labels before parse_early_param()
In the Linux kernel, the following vulnerability has been resolved: powerpc/64: Init jump labels before parseearlyparam On 64-bit, calling jumplabelinit in setupfeaturekeys is too late because static keys may be used in subroutines of parseearlyparam which is again subroutine of earlyinitdevtree...
CVE-2022-50005
The CVE-2022-50005 issue concerns Linux kernel NFC code for pn533 devices. The root cause is a use-after-free caused by a timer (cmd_timeout) not being canceled during pn532_uart_remove(), allowing a concurrent use path to dereference freed memory. The fix adds del_timer_sync() in pn532_uart_remo...
CVE-2022-50002
CVE-2022-50002 concerns the Linux kernel where the LAG logic for MLX5 was fixed so that MLX5_LAG_FLAG_NDEVS_READY is set only when both netdevices are registered. The root cause was an asymmetry in how the flag is set vs cleared, which could leave the ready state set after one PF is unloaded, lea...
CVE-2022-49992
This CVE (CVE-2022-49992) concerns the Linux kernel, where a swap-entry PFN fetch path could be misapplied during mprotect changes. Root cause: in swp_offset_pfn(), a check for swap type allowed pfn_swap_entry_to_page() to be invoked for non-write-migration entries, triggering kernel BUG at inclu...
CVE-2022-49992 mm/mprotect: only reference swap pfn page if type match
In the Linux kernel, the following vulnerability has been resolved: mm/mprotect: only reference swap pfn page if type match Yu Zhao reported a bug after the commit "mm/swap: Add swpoffsetpfn to fetch PFN from swap entry" added a check in swpoffsetpfn for swap type 1: kernel BUG at...
CVE-2022-49991
CVE-2022-49991 concerns the Linux kernel memory management subsystem, specifically the hugetlb path. In the MCOPY_ATOMIC_CONTINUE path for a non-shared VMA, pages from the page cache can be installed into ptes, but hugepage_add_new_anon_rmap is erroneously invoked for these pages, corrupting page...

CVE-2022-49974
The CVE-2022-49974 vulnerability affects the Linux kernel HID Nintendo driver (drivers/hid/hid-nintendo.c) and stems from dereferencing a NULL pointer when queuing rumble work to a destroyed workqueue after disconnection, leading to a potential crash. The issue is mitigated by avoiding usage of t...
CVE-2022-49973
The CVE-2022-49973 entry concerns a Linux kernel vulnerability in sk_msg_recvmsg triggered by an incorrect last scatter-gather (sg) check. The root cause is a change to the last sg validation (to sg_is_last()) in sk_msg_recvmsg(), but the end of the scatterlist was not marked in sockmap redirecti...
