A null pointer dereference issue was discovered in Libtiff's tif_dir.c file. This flaw allows an attacker to pass a crafted TIFF image file to the tiffcp utility, which triggers runtime error, causing an undefined behavior, resulting in an application crash, eventually leading to a denial of service.

A flaw null pointer dereference in the Linux kernel DECnet networking protocol was found. A remote user could use this flaw to crash the system.

Ubuntu Security Notice 6194-1 - Hangyu Hua discovered that the Flower classifier implementation in the Linux kernel contained an out-of-bounds write vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. Xingyuan Mo and Gengjia Chen discovered that the io_uring subsystem in the Linux kernel did not properly handle locking when IOPOLL mode is being used. A local attacker could use this to cause a denial of service.

Ubuntu Security Notice 6193-1 - Hangyu Hua discovered that the Flower classifier implementation in the Linux kernel contained an out-of-bounds write vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. It was discovered that for some Intel processors the INVLPG instruction implementation did not properly flush global TLB entries when PCIDs are enabled. An attacker could use this to expose sensitive information or possibly cause undesired behaviors.
