kernel: accel/ivpu: Add buffer overflow check in MS get_info_ioctl

A flaw was found in the Linux kernel's accel/ivpu component. This vulnerability, a buffer overflow, occurs when the firmware returns a size larger than the allocated buffer during a metric stream information query. This can lead to an incorrect buffer copy, potentially causing system instability ...

Important: Red Hat Security Advisory: kernel security, bug fix, and enhancement update

kernel: drm/amdgpu/vcn4: Prevent OOB reads when parsing IB

A flaw was found in the Linux kernel's AMD GPU Graphics Processing Unit driver, specifically within the drm/amdgpu/vcn4 component. This vulnerability allows for an out-of-bounds read when processing an Instruction Buffer IB. An attacker could potentially exploit this to read sensitive information...

kernel: fbcon: Set fb_display[i]->mode to NULL when the mode is released

A use-after-free vulnerability was identified in the Linux kernel framebuffer console fbcon subsystem. During framebuffer unregistration, the kernel freed the memory for a display mode but did not clear the corresponding fbdisplayi-mode pointer. Subsequent framebuffer ioctl operations could then...

kernel: drm/amdkfd: fix 32-bit overflow in CWSR total size calculation

A flaw was found in the Linux kernel's drm/amdkfd component. An integer overflow vulnerability exists in the calculation of a memory allocation size. When processing large input values, this calculation can result in an undersized memory region, which can then be overrun by firmware. This could...

kernel: drm/xe/eustall: Fix drm_dev_put called before stream disable in close

A flaw was found in the Linux kernel's drm/xe/eustall component. This vulnerability occurs because the drmdevput function is called before a stream is disabled and its resources are freed within xeeustallstreamclose. This timing issue can lead to a use-after-free condition, where device structure...

kernel: pppoe: reload header pointer after dev_hard_header()

A flaw was found in the Linux kernel's PPPoE Point-to-Point Protocol over Ethernet implementation. This vulnerability occurs because a pointer to network packet data is not updated after memory is reallocated, leading to the use of an outdated memory address. An attacker with local access could...

kernel: drm/amdgpu/userq: fix access to stale wptr mapping

A flaw was found in the Linux kernel. This vulnerability, located in the drm/amdgpu/userq component, involves improper handling of memory mappings. A local attacker could potentially exploit a race condition during queue creation, where a memory object is unmapped while another is being assigned ...
