A flaw was found in the USB Host Controller Driver framework in the Linux kernel. The usb_giveback_urb function has a logic loophole in its implementation. Due to the inappropriate judgment condition of the goto statement, the function cannot return under the input of a specific malformed descriptor file, so it falls into an endless loop, resulting in a denial of service.

A use-after-free flaw was found in the Linux kernel's netfilter in the way a user triggers the nft_pipapo_remove function with the element, without a NFT_SET_EXT_KEY_END. This issue could allow a local user to crash the system or potentially escalate their privileges on the system.

This Metasploit module exploits a SQL injection vulnerability in RudderStack's rudder-server, an open source Customer Data Platform (CDP). The vulnerability exists in versions of rudder-server prior to 1.3.0-rc.1. By exploiting this flaw, an attacker can execute arbitrary SQL commands, which may lead to remote code execution due to the rudder role in PostgreSQL having superuser permissions by default.

Ubuntu Security Notice 6261-1 - 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. 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.
