FreeBSD -- Multiple vulnerabilities in the sound(4) mmap path

Problem Description: The sound4 driver contained two memory-safety errors in its mmap2 support. First, dspmmapsingle validated the requested mapping by checking the sum of the user-supplied offset and length against the buffer size. This addition could overflow, so that a large offset and length...

Microsoft-signed UEFI shim bootloaders vulnerable to Secure Boot bypass

Overview Microsoft-signed UEFI bootloaders of the open-source shim project, primarily from version 0.9 and earlier, were identified as vulnerable to Secure Boot bypass. To mitigate this risk, the affected bootloaders will be added to the Microsoft UEFI Forbidden Signature Database DBX. Once the D...

CVE-2026-46276

A flaw was found in the Linux kernel's amdgpu graphics driver. This vulnerability occurs when the driver attempts to initialize zero-sized graphics memory resources on certain RDNA4 GFX 12 hardware. If a specific debugging option CONFIGDRMDEBUGMM is enabled in the kernel configuration, this...

CVE-2026-46282

A flaw was found in the Linux kernel's iio: frequency: admv1013 driver. This vulnerability occurs when the system attempts to read a device property, and an uninitialized string is used, leading to a NULL pointer dereference. This could allow a local attacker to trigger a system crash, resulting ...

CVE-2026-46287

A flaw was found in the Linux kernel's txgbe network driver. When removing a module for a copper Network Interface Card NIC with an external physical layer PHY, the driver failed to acquire the necessary RTNL Routing Netlink lock before disconnecting the PHY. This oversight can lead to an RTNL...

CVE-2026-46296

A flaw was found in the Linux kernel's s3c64xx Serial Peripheral Interface SPI driver. An issue with incorrect DMA Direct Memory Access channel deallocation during driver unbind could lead to a NULL-pointer dereference. This vulnerability can cause a system crash, resulting in a denial of service...

CVE-2026-46297

A flaw was found in the Linux kernel's libwx network driver. Incorrect handling of virtual function VF miscellaneous interrupts, specifically using requestthreadedirq with a null threaded handler and the IRQFONESHOT flag, can trigger a kernel warning. This issue may lead to system instability or...

CVE-2026-46301

A flaw was found in the Linux kernel's spi-topcliff-pch driver. This vulnerability, a use-after-free error, occurs when the driver attempts to release Direct Memory Access DMA buffers during an unbind operation without properly flushing its queue. An attacker could potentially exploit this memory...

CVE-2026-46307

A flaw was found in the Linux kernel's ath5k Wi-Fi driver. This vulnerability allows for an array-index-out-of-bounds write in the ath5ktasklettx function. An attacker could potentially trigger this by manipulating specific index values, leading to a minor data corruption. The immediate impact of...

CVE-2026-46313

A flaw was found in the Linux kernel's media subsystem, specifically within the Intel IPU6 driver. This vulnerability occurs when an error pointer is incorrectly dereferenced in an error handling path. An attacker could potentially exploit this flaw to cause a system crash, leading to a Denial of...

CVE-2026-46296

In the Linux kernel, the following vulnerability has been resolved: spi: s3c64xx: fix NULL-deref on driver unbind A change moving DMA channel allocation from probe back to s3c64xxspipreparetransfer failed to remove the corresponding deallocation from remove. Drop the bogus DMA channel release fro...

CVE-2026-46301

In the Linux kernel, the following vulnerability has been resolved: spi: topcliff-pch: fix use-after-free on unbind Give the driver a chance to flush its queue before releasing the DMA buffers on driver unbind...

CVE-2026-46276

In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix zero-size GDS range init on RDNA4 RDNA4 GFX 12 hardware removes the GDS, GWS, and OA on-chip memory resources. The gfxv120 initialisation code correctly leaves adev-gds.gdssize, adev-gds.gwssize, and adev-gds.oasi...

CVE-2026-46287

In the Linux kernel, the following vulnerability has been resolved: net: txgbe: fix RTNL assertion warning when remove module For the copper NIC with external PHY, the driver called phylinkconnectphy during probe and phylinkdisconnectphy during remove. It caused an RTNL assertion warning in...
