In the Linux kernel, the following vulnerability has been resolved: net/mlx5: HWS, fix matcher leak on resize target setup failure hwsbwcmatchermove allocates a replacement matcher before setting it as the resize target. If mlx5hwsmatcherresizesettarget fails, the replacement matcher is not...

CVE-2026-72032

CVE-2026-72032 affects the Linux kernel’s net/mlx5 HWS path. In hws_bwc_matcher_move(), a replacement matcher is allocated before resize target is set; if mlx5hws_matcher_resize_set_target() fails, the replacement is not attached and leaks. The fix destroys the replacement matcher on the resize-t...

CVE-2026-68293

A flaw was found in the net/mlx5 driver of the Linux kernel. When the driver attempts to read the MCIA register from a device advertising the mcia32dwords capability, the mlx5querymcia function can read more data than the allocated buffer can hold. This leads to a buffer overflow, which can cause...

CVE-2026-68293 net/mlx5: Fix MCIA register buffer overflow on 32 dword reads

In the Linux kernel, the following vulnerability has been resolved: net/mlx5: Fix MCIA register buffer overflow on 32 dword reads The MCIA register can return up to 32 dwords 128 bytes when the device advertises the mcia32dwords capability, but struct mlx5ifcmciaregbits only defines dword0..11,...

CVE-2026-43468

A flaw was found in the net/mlx5 component of the Linux kernel. This vulnerability involves a deadlock condition that can occur when the eswitchmodeset function attempts to acquire a devlink lock while the esw-workqueue is executing and also trying to acquire the same lock. This concurrent lock...
