The remote Redhat Enterprise Linux 9 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - kernel: powerpc/mm: Fix null-pointer dereference in pgtable_cache_add (CVE-2023-52607)

  - In the Linux kernel, the following vulnerability has been resolved: powerpc/kasan: Fix addr error caused     by page alignment In kasan_init_region, when k_start is not page aligned, at the begin of for loop, k_cur     = k_start & PAGE_MASK is less than k_start, and then `va = block + k_cur - k_start` is less than block,     the addr va is invalid, because the memory address space from va to block is not alloced by     memblock_alloc, which will not be reserved by memblock_reserve later, it will be used by other places. As     a result, memory overwriting occurs. for example: int __init __weak kasan_init_region(void *start, size_t     size) { [...] /* if say block(dcd97000) k_start(feef7400) k_end(feeff3fe) */ block = memblock_alloc(k_end
    - k_start, PAGE_SIZE); [...] for (k_cur = k_start & PAGE_MASK; k_cur < k_end; k_cur += PAGE_SIZE) { /* at     the begin of for loop * block(dcd97000) va(dcd96c00) k_cur(feef7000) k_start(feef7400) * va(dcd96c00) is     less than block(dcd97000), va is invalid */ void *va = block + k_cur - k_start; [...] } [...] } Therefore,     page alignment is performed on k_start before memblock_alloc() to ensure the validity of the VA address.
    (CVE-2024-26712)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.
