In the Linux kernel, the following vulnerability has been resolved: NFSD: Fix the behavior of READ near OFFSET_MAX Dan Aloni reports: > Due to commit 8cfb9015280d ("NFS: Always provide aligned buffers to > the RPC read layers") on the client, a read of 0xfff is aligned up > to server rsize of 0x1000. > > As a result, in a test where the server has a file of size > 0x7fffffffffffffff, and the client tries to read from the offset > 0x7ffffffffffff000, the read causes loff_t overflow in the server > and it returns an NFS code of EINVAL to the client. ... A vulnerability was found in the Linux kernel's NFSD, where improper handling of read requests near the maximum offset can lead to an integer overflow. • https://git.kernel.org/stable/c/1726a39b0879acfb490b22dca643f26f4f907da9 https://git.kernel.org/stable/c/c6eff5c4277146a78b4fb8c9b668dd64542c41b0 https://git.kernel.org/stable/c/44502aca8e02ab32d6b0eb52e006a5ec9402719b https://git.kernel.org/stable/c/0cb4d23ae08c48f6bf3c29a8e5c4a74b8388b960 https://access.redhat.com/security/cve/CVE-2022-48827 https://bugzilla.redhat.com/show_bug.cgi?id=2298166 • CWE-125: Out-of-bounds Read •

[ 63.018142] ---[ end trace ]--- Historically, the signed integer overflow sanitizer did not work in the kernel due to its interaction with `-fwrapv` but this has since been changed [1] in the newest version of Clang; It was re-enabled in the kernel with Commit 557f8c582a9ba8ab ("ubsan: Reintroduce signed overflow sanitizer"). Let's rework this overflow checking logic to not actually perform an overflow during the check itself, thus avoiding the UBSAN splat.
