CVE-2022-50036

CVE-2022-50036 affects the Linux kernel component drm/sun4i: dsi. The underflow occurred when computing packet sizes due to subtracting packet overhead with unsigned arithmetic; with a short sync pulse the subtraction could wrap to a large unsigned value. The remediation is a fix that uses signed...

CVE-2022-50032

CVE-2022-50032 concerns the Linux kernel USB Renesas driver fix for a refcount leak. The issue arises in usbhs_rza1_hardware_init() where of_find_node_by_name() returns a node pointer with an elevated refcount; the correct handling is to call of_node_put() when the node is no longer needed. The c...

CVE-2022-50026 habanalabs/gaudi: fix shift out of bounds

In the Linux kernel, the following vulnerability has been resolved: habanalabs/gaudi: fix shift out of bounds When validating NIC queues, queue offset calculation must be performed only for NIC queues...

CVE-2022-50022

CVE-2022-50022 is a Linux kernel vulnerability in the md driver (RAID5) that can cause a use-after-free. The issue arises because raid5_release_stripe(sh) drops a reference to sh, but sh is later dereferenced (sh->batch_head) in the same function. The patch fixes this by moving raid5_release_s...

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.
