USN-4951-1: Flatpak vulnerability Anton Lydike discovered that Flatpak did not properly handle special tokens in desktop files. An attacker could use this to specially craft a Flatpak application that could escape sandbox confinement. Source: USN-4951-1: Flatpak vulnerability

USN-4950-1: Linux kernel vulnerabilities Ryota Shiga discovered that the eBPF implementation in the Linux kernel did not properly verify that a BPF program only reserved as much memory for a ring buffer as was allocated. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2021-3489) Manfred Paul discovered that the eBPF implementation in the Linux kernel did not properly track bounds on bitwise operations. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2021-3490) Billy Jheng Bing-Jhong discovered that the io_uring implementation of the Linux kernel did not properly enforce the MAX_RW_COUNT limit in some situations. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2021-3491) Norbert Slusarek discovered that the CAN ISOTP [ more… ]

USN-4949-1: Linux kernel vulnerabilities Ryota Shiga discovered that the eBPF implementation in the Linux kernel did not properly verify that a BPF program only reserved as much memory for a ring buffer as was allocated. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code.

(CVE-2021-3490) Billy Jheng Bing-Jhong discovered that the io_uring implementation of the Linux kernel did not properly enforce the MAX_RW_COUNT limit in some situations. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2021-3491) It was discovered that the Nouveau GPU [ more… ]

USN-4948-1: Linux kernel (OEM) vulnerabilities Ryota Shiga discovered that the eBPF implementation in the Linux kernel did not properly verify that a BPF program only reserved as much memory for a ring buffer as was allocated. A local attacker could use this to cause a denial of service (system crash) or execute arbitrary code.
