SUSE CVE-2024-38620

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: HCI: Remove HCIAMP support Since BTHS has been remove HCIAMP controllers no longer has any use so remove it along with the capability of creating AMP controllers. Since we no longer need to differentiate between AMP an...

CVE-2024-38620

Summary: Linux kernel Bluetooth stack removed HCI_AMP support; with BT_HS removed, AMP controllers are no longer used, leading to removal of AMP capability and hdev->dev_type. What changes: removal of HCI_AMP controllers, elimination of AMP vs Primary differentiation, and associated dev_type f...

kernel: race condition between HCIUARTSETPROTO and HCIUARTGETPROTO in hci_uart_tty_ioctl

A NULL pointer dereference flaw was found in the Linux kernel’s Bluetooth HCI UART driver. This flaw allows a local user to crash the system...

PT-2024-8486 · Linux +4 · Linux Kernel +4

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue is related to a double free error in the hci devcd append function, which can cause a denial of service. The error occurs when the skb is freed on error, and the caller also...

DEBIAN-CVE-2024-26889

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcicore: Fix possible buffer overflow struct hcidevinfo has a fixed size name8 field so in the event that hdev-name is bigger than that strcpy would attempt to write past its size, so this fixes this problem by switchi...

UBUNTU-CVE-2023-52518

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcicodec: Fix leaking content of localcodecs The following memory leak can be observed when the controller supports codecs which are stored in localcodecs list but the elements are never freed: unreferenced object...

USN-6520-1: Linux kernel (StarFive) vulnerabilities

Ivan D Barrera, Christopher Bednarz, Mustafa Ismail, and Shiraz Saleem discovered that the InfiniBand RDMA driver in the Linux kernel did not properly check for zero-length STAG or MR registration. A remote attacker could possibly use this to execute arbitrary code. CVE-2023-25775 Yu Hao and...

USN-6516-1: Linux kernel (Intel IoTG) vulnerabilities

Ivan D Barrera, Christopher Bednarz, Mustafa Ismail, and Shiraz Saleem discovered that the InfiniBand RDMA driver in the Linux kernel did not properly check for zero-length STAG or MR registration. A remote attacker could possibly use this to execute arbitrary code. CVE-2023-25775 Yu Hao and...

USN-6462-2: Linux kernel (IoT) vulnerabilities

Seth Jenkins discovered that the Linux kernel did not properly perform address randomization for a per-cpu memory management structure. A local attacker could use this to expose sensitive information kernel memory or in conjunction with another kernel vulnerability. CVE-2023-0597 Yu Hao and Weite...

OESA-2023-1783 kernel security update

The Linux Kernel, the operating system core itself. Security Fixes: An issue was discovered in the Linux kernel through 6.0.6. drivers/char/pcmcia/cm4040cs.c has a race condition and resultant use-after-free if a physically proximate attacker removes a PCMCIA device while calling open, aka a race...
