CVE-2022-49567

The CVE-2022-49567 issue is a Linux kernel vulnerability in mm/mempolicy where uninitialized nodemask data can be accessed when policy mode is MPOL_LOCAL, leading to potential read of pol->w.cpuset_mems_allowed during mpol_rebind_policy. The root cause is that mpol_set_nodemask() does not init...

CVE-2022-49507

CVE-2022-49507 affects the Linux kernel regulator driver for the da9121 (regulator/da9121-regulator.c). The issue arises when da9121_assign_chip_model() accesses regmap without it being initialized due to an invalid chip->subvariant_id (set to -EINVAL by a malformed device tree). This leads to...
