kernel: out-of-bounds access in relay_file_read

An out-of-bounds OOB memory access flaw was found in the Linux kernel in relayfilereadstartpos in kernel/relay.c in the relayfs. This flaw allows a local attacker to crash the system or leak kernel internal information...

CVE-2023-52489

A race condition was found on a PFN in the Linux Kernel, which can fall into the device memory region with the system memory configuration. Normal zone start and end PFNs contain the device memory PFNs as well, and the compaction triggered will try on the device memory PFNs and end up in NOP. Thi...
