CVE-2026-93523

A flaw was found in xorg-x11-server. A local authenticated client can exploit this flaw by sending a crafted input device ungrab request with an unvalidated modifier value. This lack of validation causes the server to perform an out-of-bounds write on the heap, resulting in memory corruption that...

gvcidrv64

해커 여러분. GVCIDrv64.sys는 Gigabyte의 BIOS 유틸리티와 함께 제공되는 서명된 커널 드라이버입니다. 이 드라이버는 보안 서술자 없이 \.\GVCIDrv64를 생성하므로, 로컬 사용자라면 누구나 관리자 권한이나 UAC 없이 이를 열 수 있습니다. 이 드라이버는 접근 제어가 전혀 없는 3개의 IOCTL을 노출합니다: 물리 메모리 32 MB 매핑0x9C406580, 매핑 해제0x9C406584, 그리고 1/2/4 바이트의 원시 I/O 포트 읽기/쓰기0x9C406588입니다. 핵심은 이 중 2개가 어떻게...

kernel: RDMA/rxe: Reject non-8-byte ATOMIC_WRITE payloads

A flaw was found in the Linux kernel's RDMA Remote Direct Memory Access subsystem, specifically within the rxe driver. A remote attacker could exploit this vulnerability by sending a specially crafted ATOMICWRITE request with a zero-byte payload. This improper handling of non-8-byte ATOMICWRITE...

kernel: smb: client: fix query_info() replay double-free

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability, a double-free error, occurs when the queryinfo replay mechanism attempts to free a response buffer that has already been released. This can happen if an error occurs during the initialization of an SMB2...

kernel: ipv6: exthdrs: refresh nh after handling HAO option

A flaw was found in the Linux kernel's IPv6 extension header processing. When processing the Home Address Option HAO, the cached network header pointer may become invalid if the packet's memory is reallocated. This can lead to incorrect parsing of subsequent IPv6 Type-Length-Value TLV options,...

kernel: smb: client: fix double-free in SMB2_flush() replay

A flaw was found in the Linux kernel's Server Message Block SMB client. This vulnerability, a double-free error within the SMB2flush replay mechanism, occurs when the system attempts to free a memory buffer twice. A malicious SMB server could exploit this by sending a specially crafted flush...
