Descriptions

A flaw incorrect access control in the Linux kernel USB core subsystem was found in the way user attaches usb device. A local user could use this flaw to crash the system.

Se encontró un fallo en el control de acceso incorrecto en el subsistema central USB del kernel de Linux en la forma en que el usuario conecta el dispositivo USB. Un usuario local podría utilizar este fallo para bloquear el sistema.

An incorrect access control flaw was found in the Linux kernel USB core subsystem. When attaching a malicious usb device, the recursive locking violation in usb-storage can cause the kernel to deadlock. This issue could allow a local user to crash the system.

Xuewei Feng, Chuanpu Fu, Qi Li, Kun Sun, and Ke Xu discovered that the TCP implementation in the Linux kernel did not properly handle IPID assignment. A remote attacker could use this to cause a denial of service or inject forged data. Ke Sun, Alyssa Milburn, Henrique Kawakami, Emma Benoit, Igor Chervatyuk, Lisa Aichele, and Thais Moreira Hamasaki discovered that the Spectre Variant 2 mitigations for AMD processors on Linux were insufficient in some situations. A local attacker could possibly use this to expose sensitive information.
