CVE-2023-53070

CVE-2023-53070 affects the Linux kernel: when PPTT is absent, multiple CPUs could call acpi_get_pptt() in atomic context, risking a sleep waiting on a mutex and a kernel crash trace. The fix updates acpi_get_pptt() to return NULL if PPTT is not available, avoiding sleeps in atomic context and pre...

CVE-2023-53069

CVE-2023-53069 concerns the Linux kernel octeontx2-vf driver: missing free for alloc_percpu leading to a memory leak in vf->hw.lmt_info. The fix adds free_percpu for the allocated structure, mirroring the existing pf->hw.lmt_info cleanup in otx2_pf.c. This change reduces a local memory leak...

CVE-2023-53068

In the Linux kernel, the following vulnerability has been resolved: net: usb: lan78xx: Limit packet length to skb-len Packet length retrieved from descriptor may be larger than the actual socket buffer length.
