Summary
linux-gcp-5.15 vulnerabilities
Details

Daniel Moghimi discovered that some Intel(R) Processors did not properly clear microarchitectural state after speculative execution of various instructions. A local unprivileged user could use this to obtain to sensitive information. (CVE-2022-40982)

Tavis Ormandy discovered that some AMD processors did not properly handle speculative execution of certain vector register instructions. A local attacker could use this to expose sensitive information. (CVE-2023-20593)

Ye Zhang and Nicolas Wu discovered that the io_uring subsystem in the Linux kernel did not properly handle locking for rings with IOPOLL, leading to a double-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-21400)

It was discovered that the universal 32bit network packet classifier implementation in the Linux kernel did not properly perform reference counting in some situations, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-3609)

It was discovered that the netfilter subsystem in the Linux kernel did not properly handle certain error conditions, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-3610)

It was discovered that the Quick Fair Queueing network scheduler implementation in the Linux kernel contained an out-of-bounds write vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-3611)

It was discovered that the network packet classifier with netfilter/firewall marks implementation in the Linux kernel did not properly handle reference counting, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-3776)

Kevin Rich discovered that the netfilter subsystem in the Linux kernel did not properly handle table rules flush in certain circumstances. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-3777)

Kevin Rich discovered that the netfilter subsystem in the Linux kernel did not properly handle rule additions to bound chains in certain circumstances. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-3995)

It was discovered that the netfilter subsystem in the Linux kernel did not properly handle PIPAPO element removal, leading to a use-after-free vulnerability. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-4004)

Kevin Rich discovered that the netfilter subsystem in the Linux kernel did not properly handle bound chain deactivation in certain circumstances. A local attacker could possibly use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2023-4015)
