CVE-2022-49711

The CVE-2022-49711 issue affects the Linux kernel in the bus: fsl-mc-bus path. Root cause: in fsl_mc_bus_remove(), mc->root_mc_bus_dev->mc_io is passed to fsl_destroy_mc_io() after mc->root_mc_bus_dev has already been freed in fsl_mc_device_remove(), causing a KASAN use-after-free. Mitig...

CVE-2022-49710

CVE-2022-49710 affects the Linux kernel's device-mapper dm-log path (dm-mirror) where rounding bitset_size to 32 bits causes an out-of-bounds access on 64-bit architectures when find_next_zero_bit_le reads the bitmap. The root cause is using unsigned long pointers for the bitmap, allowing a 4-byt...
