CVE-2026-68261 drm/imagination: fix error checking of pvr_vm_context_lookup()

In the Linux kernel, the following vulnerability has been resolved: drm/imagination: fix error checking of pvrvmcontextlookup Since pvrvmcontextlookup returns either NULL or a pointer, then stop using ISERR for checking the return value. Using ISERR leads to the kernel oops reported below. It can...

CVE-2026-68235 drm/amd/display: dce100: skip non-DP stream encoders for DP MST

In the Linux kernel, the following vulnerability has been resolved: drm/amd/display: dce100: skip non-DP stream encoders for DP MST On DCE8-class ASICs e.g. Bonaire, the resource pool contains digital DIG stream encoders plus one analog DAC encoder. When assigning a stream encoder for a second...

CVE-2026-68235

The CVE refers to drm/amd/display (dce100) in the Linux kernel. Root cause: when assigning a stream encoder for a second DisplayPort MST stream on DCE8-class ASICs, if the preferred digital encoder is already acquired, the code can fall back to an analog DAC encoder whose funcs table lacks DP hoo...

CVE-2026-68194 wifi: mt76: mt7921: drop TXRX_NOTIFY on non-mmio buses

In the Linux kernel, the following vulnerability has been resolved: wifi: mt76: mt7921: drop TXRXNOTIFY on non-mmio buses PKTTYPETXRXNOTIFY is an mmio-only event, but mt7921rxcheck and mt7921queuerxskb dispatch it to mt7921mactxfree on every bus. mt7921mactxfree cleans the DMA tx queues with...

CVE-2026-64297

A flaw was found in the Linux kernel. An unchecked return value in the moduleextendmaxpages function within the module decompression logic can lead to a null pointer dereference. This vulnerability can be triggered if memory allocation fails during module loading, resulting in a kernel oops. This...

CVE-2026-64538

CVE-2026-64538 concerns a Linux kernel vulnerability where fib6_nh_mtu_change() dereferences idev->cnf.mtu6 after re-fetching idev with __in6_dev_get(arg->dev) without a NULL check. This can occur because addrconf_ifdown() clears dev->ip6_ptr after tb6_lock is released, allowing an RA-dr...
