kernel: Linux kernel: Use-After-Free in net/gro due to improper handling of zerocopy skbs

A flaw was found in the Linux kernel's Generic Receive Offload GRO networking subsystem. This vulnerability occurs when skbgroreceive attempts to merge zerocopy socket buffers skbs without properly managing page reference counts, specifically when the SKBFLMANAGEDFRAGREFS flag is set. An attacker...

The vulnerability of the Microsoft .NET Framework software lies in the possibility of an operation occurring outside the buffer boundaries in memory, which allows a malicious actor to cause a system failure.

The vulnerability of the Microsoft .NET Framework software platform is related to the execution of operations outside the buffer in memory. Exploitation of this vulnerability can allow a remote attacker to cause service interruptions...

CVE-2026-63970

A flaw was found in the Linux kernel's vsock/virtio transport. This vulnerability occurs when the system processes zerocopy socket buffers skbs and encounters an error during memory allocation for fixed-buffer vectored data. The system may attempt to free memory incorrectly, leading to a...

CVE-2026-47714

libheif is a HEIF and AVIF file format decoder and encoder. In versions 1.21.2 and prior, the inline mask parsing code in libheif/region.cc contains an integer overflow. Both width and height are unsigned int 32-bit values parsed from the HEIF file. Their product can exceed UINT32MAX, wrapping to...

CVE-2026-63901

A flaw was found in the Linux kernel's digiacceleport USB serial driver. A malicious Universal Serial Bus USB device could report smaller bulk-out buffers than expected. This lack of proper size validation could lead to out-of-bounds memory accesses or slab corruption, potentially causing system...

CVE-2026-63822

A flaw was found in the Linux kernel's ath11k Wi-Fi driver. This vulnerability, a double free, occurs when memory buffers are incorrectly released twice during the device unbinding process after an initial firmware initialization error. This can lead to system instability or a kernel crash,...

SUSE CVE-2026-63822

In the Linux kernel, the following vulnerability has been resolved: wifi: ath11k: fix warning when unbinding If there is an error during some initialization related to firmware, the buffers dp-txringi.txstatus are released. However this is released again when the device is unbinded ath11kpci, and...

CVE-2026-63928

In the Linux kernel, the following vulnerability has been resolved: USB: serial: omninet: fix memory corruption with small endpoint Make sure that the bulk-out buffers are at least as large as the hardcoded transfer size to avoid user-controlled slab corruption should a malicious device report a...

CVE-2026-64091 batman-adv: tt: fix TOCTOU race for reported vlans

In the Linux kernel, the following vulnerability has been resolved: batman-adv: tt: fix TOCTOU race for reported vlans The local TT based TVLV is generated by first checking the number of VLANs which have at least one TT entry. A new buffer with the correct size for the VLANs is then allocated...

CVE-2026-64056 net: ethernet: cortina: Make RX SKB per-port

In the Linux kernel, the following vulnerability has been resolved: net: ethernet: cortina: Make RX SKB per-port The SKB used to assemble packets from fragments in gmacrx is static local, but the Gemini has two ethernet ports, meaning there can be races between the ports on a bad day if a device ...
