kernel: cifs: fix oops during encryption

An out-of-bounds memory access vulnerability exists in the linux kernel, such that A stack-allocated buffer backed by vmalloc was passed into crypto code scatterwalkmapandcopy → memcpy where a cross-page write occurred. This ended up hitting a read-only mapping, causing a page-level fault and...

CVE-2024-50278 dm cache: fix potential out-of-bounds access on the first resume

In the Linux kernel, the following vulnerability has been resolved: dm cache: fix potential out-of-bounds access on the first resume Out-of-bounds access occurs if the fast device is expanded unexpectedly before the first-time resume of the cache table. This happens because expanding the fast...
