CVE-2023-54283
CVE-2023-54283 is a Linux kernel vulnerability related to a data-race in the BPF LRU list code. Kernel Concurrency Sanitizer detected a race on accessing node->ref in __bpf_lru_list_rotate/__htab_lru_percpu_map_update_elem, leading to a write of 1 byte and a read of 1 byte across CPUs. The fix...
CVE-2023-54165
CVE-2023-54165: In the Linux kernel zsmalloc, the LRU list update was moved from zs_map_object() to zs_malloc(), which under concurrent store/reclaim can trigger list corruption and crashes under memory pressure. The issue affects Linux kernels prior to 5.19.0-0 fbk3 rc3 hoangnhatpzsdynshrv41_108...
