A flaw was found in the way the Linux kernel's networking subsystem handled the write queue between TCP disconnection and re-connections. A local attacker could use this flaw to trigger multiple use-after-free conditions potentially escalating their privileges on the system.
In the Linux kernel, the following vulnerability has been resolved:
netfilter: nftables: mark set as dead when unbinding anonymous set with timeout
The Linux kernel CVE team has assigned CVE-2024-26643 to this issue.
Upstream advisory: https://lore.kernel.org/linux-cve-announce/2024032150-CVE-2024-26643-4f9d@gregkh/T
A race condition was found in the Linux kernel's net/bluetooth in {conn,adv}{min,max}intervalset() function. This can result in I2cap connection or broadcast abnormality issue, possibly leading to denial of service.
A race condition was found in the Linux kernel's net/bluetooth device driver in conninfo{min,max}ageset() function. This can result in integrity overflow issue, possibly leading to bluetooth connection abnormality or denial of service.
A use-after-free in the mac80211 stack when parsing a multi-BSSID element in the Linux kernel 5.2 through 5.19.x before 5.19.16 could be used by attackers (able to inject WLAN frames) to crash the kernel and potentially execute code.
A use-after-free flaw was found in bssrefget in the net/wireless/scan.c in the Linux kernel. This issue can lead to a denial of service or arbitrary code execution.
A list corruption flaw was found in cfg80211addnontranslist in the net/wireless/scan.c function in the Linux kernel. This flaw could lead to a denial of service.
Google Chromium Intents contains an improper input validation vulnerability that allows a remote attacker to arbitrarily browser to a malicious URL via a crafted HTML page. This vulnerability could affect multiple web browsers that utilize Chromium, including, but not limited to, Google Chrome, Microsoft Edge, and Opera.
In the Linux kernel, the following vulnerability has been resolved:
firmware: armscmi: Harden accesses to the reset domains
Accessing reset domains descriptors by the index upon the SCMI drivers requests through the SCMI reset operations interface can potentially lead to out-of-bound violations if the SCMI driver misbehave.
Add an internal consistency check before any such domains descriptors accesses.

An issue was discovered in Arm Mbed TLS before 2.23.0. Because of a side channel in modular exponentiation, an RSA private key used in a secure enclave could be disclosed.
From https://www.openwall.com/lists/oss-security/2021/08/30/1:
Security vulnerabilities were identified in the open source NTFS-3G and NTFSPROGS software. These vulnerabilities were confirmed and resolved. To our knowledge, these vulnerabilities have not been exploited.
These vulnerabilities may allow an attacker using a maliciously crafted NTFS-formatted image file or external storage to potentially execute arbitrary privileged code, if the attacker has either local access and the ntfs-3g binary is setuid root, or if the attacker has physical access to an external port to a computer which is configured to run the ntfs-3g binary or one of the ntfsprogs tools when the external storage is plugged into the computer. These vulnerabilities result from incorrect validation of some of the NTFS metadata that could potentially cause buffer overflows, which could be exploited by an attacker. Common ways for attackers to gain physical access to a machine is through social engineering or an evil maid attack on an unattended computer.
We recommend installing and applying the update with the security fixes, and advise to follow security guidance and frameworks such as NIST for assessing and improving an organization’s abilities to prevent, detect, and respond to security threats and cyber attacks.
AFFECTED PRODUCTS: All previous versions of open source NTFS-3G and NTFSPROGS.
WORKAROUND: None
