Elasticsearch version 8.5.3 stack overflow proof of concept exploit.
3ea73849caae7368d08d81cb21e393baddfab08e0fc2108b64083363b66bb17aUbuntu Security Notice 6283-1 - Ruihan Li discovered that the bluetooth subsystem in the Linux kernel did not properly perform permissions checks when handling HCI sockets. A physically proximate attacker could use this to cause a denial of service. Zheng Zhang discovered that the device-mapper implementation in the Linux kernel did not properly handle locking during table_clear operations. A local attacker could use this to cause a denial of service.
d89ea852ace9ebfc7bd58b09a638e52edb508a4626f5a1fe5c5fc2bf4bbdc318Ubuntu Security Notice 6260-1 - It was discovered that the NTFS file system implementation in the Linux kernel did not properly check buffer indexes in certain situations, leading to an out-of-bounds read vulnerability. A local attacker could possibly use this to expose sensitive information. Stonejiajia, Shir Tamari and Sagi Tzadik discovered that the OverlayFS implementation in the Ubuntu Linux kernel did not properly perform permission checks in certain situations. A local attacker could possibly use this to gain elevated privileges.
a4384a0d58c965d16d9a12fe71bc79afb9b36f12a4660d6419a9dae8338f976aUbuntu Security Notice 6254-1 - Jordy Zomer and Alexandra Sandulescu discovered that syscalls invoking the do_prlimit function in the Linux kernel did not properly handle speculative execution barriers. A local attacker could use this to expose sensitive information. It was discovered that a race condition existed in the btrfs file system implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service or possibly expose sensitive information.
0faaa1a4c904d2777eb8f39748a9d767eddb9f41659d19079b8dcbea4f5d81efUbuntu Security Notice 6252-1 - It was discovered that the ext4 file system implementation in the Linux kernel contained a use-after-free vulnerability. An attacker could use this to construct a malicious ext4 file system image that, when mounted, could cause a denial of service. It was discovered that the sound subsystem in the Linux kernel contained a race condition in some situations. A local attacker could use this to cause a denial of service.
f33849bf32c8784dc2dc942eddd765a6da4ead4a24f6749cde835abee1fdbf59Ubuntu Security Notice 6231-1 - It was discovered that the XFS file system implementation in the Linux kernel did not properly perform metadata validation when mounting certain images. An attacker could use this to specially craft a file system image that, when mounted, could cause a denial of service. It was discovered that the IP-VLAN network driver for the Linux kernel did not properly initialize memory in some situations, leading to an out-of- bounds write vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code.
