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-2026-46292

A flaw was found in the Linux kernel's generic power domain genpd component. When a virtual device is detached from a power management PM domain, the pmruntimedisable function is not called, leaving runtime PM enabled for the detached device. This oversight can lead to critical errors, including ...

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-2026-46305

A flaw was found in the Linux kernel, specifically within the rtl8723bs staging driver's osdep module. The rtwcbufalloc function does not properly validate the return value of a memory allocation, leading to an unconditional dereference of a potentially NULL pointer. This vulnerability could allo...

CVE-2026-46310

A flaw was found in the Linux kernel's media: renesas: vsp1 component. When unloading the module on generation 4 hardware, an incorrect cleanup function is called, leading to a NULL pointer dereference. This vulnerability can be triggered by a local attacker, potentially causing a system crash an...

K000161631: libmspack vulnerability CVE-2018-18585

Security Advisory Description chmdreadheaders in mspack/chmd.c in libmspack before 0.8alpha accepts a filename that has '\0' as its first or second character such as the "/\0" name. CVE-2018-18585 Impact There is no impact; F5 products are not affected by this vulnerability. Security Advisory...

CVE-2026-46313

In the Linux kernel, the following vulnerability has been resolved: media: intel/ipu6: fix error pointer dereference In a error path isp-psys is confirmed to be an error pointer not NULL so this condition is true and the error pointer is dereferenced. So isp-psys should be set to NULL before goin...

CVE-2026-46305

In the Linux kernel, the following vulnerability has been resolved: staging: rtl8723bs: osdep: avoid NULL pointer dereference in rtwcbufalloc The return value of kzallocflex is used without ensuring that the allocation succeeded, and the pointer is dereferenced unconditionally. Guard the access t...

CVE-2026-46310

In the Linux kernel, the following vulnerability has been resolved: media: renesas: vsp1: Fix NULL pointer deref on module unload When unloading the module on gen 4, we hit a NULL pointer dereference. This is caused by the cleanup code calling vsp1drmcleanup where it should be calling...

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-2026-46284

In the Linux kernel, the following vulnerability has been resolved: mm/hugetlb: fix early boot crash on parameters without '=' separator If hugepages, hugepagesz, or defaulthugepagesz are specified on the kernel command line without the '=' separator, early parameter parsing passes NULL to...

CVE-2026-46282

In the Linux kernel, the following vulnerability has been resolved: iio: frequency: admv1013: fix NULL pointer dereference on str When devicepropertyreadstring fails, str is left uninitialized but the code falls through to strcmpstr, ..., dereferencing a garbage pointer. Replace manual read/strcm...
