kernel: xfs: don't walk off the end of a directory data block

A vulnerability was found in the Linux kernel in the xfsdir2dataunused and xfsdir2dataentry functions where a lack of proper sanity checks while handling directory data blocks can lead to out-of-bounds memory access. This can result in undefined system behavior or crashes...

kernel: NFSD: Fix ia_size underflow

A vulnerability was found in the Linux kernel's NFSD, where an underflow in the iasize field can occur due to incorrect handling of file size types. When an NFS client sends a file size greater than the maximum value the system can handle, it can lead to an underflow in the iasize variable, causi...

kernel: NFSD: Fix NFSv3 SETATTR/CREATE's handling of large file sizes

A vulnerability was found in the Linux kernel's NFSD, specifically in the handling of large file sizes during NFSv3 SETATTR and CREATE operations. The iasize field, being a signed 64-bit type, can lead to unexpected behavior when clients send size values larger than the maximum allowed. This...

The vulnerability of the btrfs component of the Linux operating system’s kernel, related to writing beyond the memory boundaries, allows a hacker to trigger a service failure.

The vulnerability of the btrfs component in Linux operating systems relates to the copying of overly large compressed segments. The compressed length may be corrupted, resulting in a much larger amount of memory being allocated for the buffer. Exploiting this vulnerability can allow an attacker t...
