CVE-2022-50091 concerns the Linux kernel where the boot-time parameter csdlock_debug was parsed via early_param, enabling static_branch in a manner that could dereference NULL under specific sparse memory configurations (arm64 with CONFIG_SPARSEMEM and SPARSEMEM_VMEMMAP settings, and powerpc due ...

CVE-2022-50059

CVE-2022-50059 is documented as a Linux kernel vulnerability affecting the Ceph integration: when handle_cap_grant is called on an IMPORT operation, the snap_rwsem is held and not reliably released, which could lead to a deadlock. The issue is described across multiple vendor advisories (EulerOS,...

CVE-2022-50053

CVE-2022-50053 concerns the Linux kernel iavf driver: a reset error handling path could lead to deadlock due to double napi_disable and a stuck iavf_remove when VF removal occurs during rapid resets. The fix removes the call to iavf_close in reset error handling and instead calls iavf_disable_vf ...

CVE-2022-50047

The CVE-2022-50047 issue affects the Linux kernel’s net: dsa mv88e6060 code. When a port is neither a CPU port nor a user port, cpu_dp can be NULL, causing a NULL pointer dereference and kernel crash during mv88e6060_setup_port(). This is a local impact vulnerability that leads to a crash; connec...
