RHEL 8 : kernel (RHSA-2024:0724)

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2024:0724 advisory. The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fixes: kernel: use-after-free in schqfq netwo...

The cifs_iovec_write function in fs/cifs/file.c in the Linux kernel through 3.13.5 does not properly handle uncached write operations that copy fewer than the requested number of bytes which allows local users to obtain sensitive information from kernel memory cause a denial of service (memory corruption and system crash) or possibly gain privileges via a writev system call with a crafted pointer.
