USN-6819-4 linux-oracle-6.5 vulnerabilities

Alon Zahavi discovered that the NVMe-oF/TCP subsystem in the Linux kernel did not properly validate H2C PDU data, leading to a null pointer dereference vulnerability. A remote attacker could use this to cause a denial of service system crash. CVE-2023-6356, CVE-2023-6535, CVE-2023-6536 Chenyuan...

SUSE CVE-2024-38604

In the Linux kernel, the following vulnerability has been resolved: block: refine the EOF check in blkdeviomapbegin blkdeviomapbegin rounds down the offset to the logical block size before stashing it in iomap-offset and checking that it still is inside the inode size. Check the isize check to th...
