Summary
linux-gcp-5.15, linux-gkeop-5.15 vulnerabilities
Details

It was discovered that the NTFS file system implementation in the Linux kernel did not properly validate MFT flags in certain situations. An attacker could use this to construct a malicious NTFS image that, when mounted and operated on, could cause a denial of service (system crash). (CVE-2022-48425)

Zi Fan Tan discovered that the binder IPC implementation in the Linux kernel contained 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-2023-21255)

It was discovered that a race condition existed in the f2fs file system in the Linux kernel, leading to a null pointer dereference vulnerability. An attacker could use this to construct a malicious f2fs image that, when mounted and operated on, could cause a denial of service (system crash). (CVE-2023-2898)

It was discovered that the DVB Core driver in the Linux kernel did not properly handle locking events in certain situations. A local attacker could use this to cause a denial of service (kernel deadlock). (CVE-2023-31084)

Yang Lan discovered that the GFS2 file system implementation in the Linux kernel could attempt to dereference a null pointer in some situations. An attacker could use this to construct a malicious GFS2 image that, when mounted and operated on, could cause a denial of service (system crash). (CVE-2023-3212)

It was discovered that the KSMBD implementation in the Linux kernel did not properly validate buffer sizes in certain operations, leading to an out-of- bounds read vulnerability. A remote attacker could use this to cause a denial of service (system crash) or possibly expose sensitive information. (CVE-2023-38426, CVE-2023-38428)

It was discovered that the KSMBD implementation in the Linux kernel did not properly calculate the size of certain buffers. A remote attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2023-38429)
