kernel: smb: client: fix OOB read/write from unvalidated DataOffset in coalesce_t2()
A flaw was found in the Linux kernel's Server Message Block SMB client. The coalescet2 function processes server-supplied DataOffset fields without proper validation against buffer boundaries. A remote attacker could exploit this by crafting malicious SMB responses. This could lead to out-of-boun...
kernel: ipv4: validate checksum_start before completing checksum
A flaw was found in the Linux kernel. A local attacker or untrusted guest virtual machine can exploit this vulnerability by transmitting network packets containing malformed checksum metadata into the IPv4 networking subsystem. This failure to validate checksum metadata can corrupt memory during...
kernel: ipv4: validate checksum_start before completing checksum
A flaw was found in the Linux kernel. A local attacker or untrusted guest virtual machine can exploit this vulnerability by transmitting network packets containing malformed checksum metadata into the IPv4 networking subsystem. This failure to validate checksum metadata can corrupt memory during...
SUSE-SU-2026:4776-1 Security update for the Linux Kernel (Live Patch 86 for SUSE Linux Enterprise 12 SP5)
This update for the SUSE Linux Enterprise Kernel 4.12.14-122.323 fixes various security issues: The following security issues were fixed: - CVE-2026-63887: scsi: target: iscsi: Bound iscsiencodetextoutput appends to rspbuf bsc1272386. - CVE-2026-68158: libceph: Fix multiplication overflow in...
CVE-2026-64603
A flaw was found in the Linux kernel's intel-hid driver. A race condition can occur in the ACPI Advanced Configuration and Power Interface notify handler when processing tablet-mode events on convertible or detachable devices. If two events are processed concurrently, the input device may be...
CVE-2026-64593
A flaw was found in the btrfs filesystem of the Linux kernel. A local user could trigger a system crash by attempting to perform a trim operation on a storage device that was previously unavailable but has since reconnected and is not writeable. This issue arises from a synchronization problem...
CVE-2026-64591
A flaw was found in the Linux kernel's Intel IOMMU driver. This issue occurs because the driver attempts to disable I/O Page Fault IOPF handling for devices that never had it enabled, specifically when Shared Virtual Addressing SVA is used on hardware that does not support the PCI Page Request...
CVE-2026-64590
A flaw was found in the Linux kernel's dma-buf subsystem, specifically within the udmabuf component. When the CONFIGDMAAPIDEBUGSG option is enabled, importing a udmabuf into a Direct Rendering Manager DRM driver can trigger a spurious warning about overlapping cacheline mappings. This occurs...
CVE-2026-89855
A flaw was found in the Linux kernel's scsi: qla2xxx component. A local attacker could exploit a race condition in the flash version read handler. By concurrently triggering a sysfs reset operation and other flash operations, an attacker could corrupt flash register reads. This could lead to data...
CVE-2026-89790
A flaw was found in the Linux kernel's IPv6 networking subsystem. A race condition can occur during IPv6 multipath route rebalancing, where a concurrent update can lead to a divide-by-zero error. This vulnerability can cause the kernel to crash, resulting in a Denial of Service DoS for the affect...
CVE-2026-89784
A flaw was found in the Linux kernel's SUNRPC component. When an in-kernel RPC service registers with the local rpcbind under memory pressure, a failure in memory allocation can lead to a NULL pointer being dereferenced. This unchecked NULL pointer can cause the kernel to crash, resulting in a...
CVE-2026-89577
A flaw was found in the Linux kernel's device mapper I/O dm-io and RAID1 dm-raid1 components. Incorrect error handling for non-retryable errors such as BLKSTSNOTSUPP and BLKSTSINVAL could lead to misbehavior when a user utilizes unaligned bio vectors on dm-raid1. This misbehavior could potentiall...
CVE-2026-89562
A flaw was found in the Linux kernel's IPv6 Generic Routing Encapsulation GRE subsystem. The kernel incorrectly calculates the hardware header length for Non-Broadcast Multiple Access NBMA tunnel interfaces by improperly accumulating the underlying device's header length. A local authenticated...
CVE-2026-80913
A flaw was found in the Linux kernel's SELinux subsystem. An attacker with local access could exploit this by providing a specially crafted SELinux policy. This policy, containing an incorrect number of defined boolean values, would cause the kernel to attempt to access an invalid memory location...
CVE-2026-80912
A flaw was found in the Linux kernel's SELinux subsystem. When processing security class values, the securitygetclasses function could return a null pointer if a class value was not properly defined by the security policy. This could lead to a null pointer dereference, potentially causing a syste...
CVE-2026-80892
A flaw was found in the Linux kernel's EROFS Enhanced Read-Only File System component. On systems with a high number of processing units, mounting a specially crafted EROFS image can cause the kernel to allocate an excessive amount of memory for LZMA decompression streams. This uncontrolled memor...
CVE-2026-80888
A flaw was found in the drm/vmwgfx component of the Linux kernel. An unprivileged client can exploit this vulnerability by passing a specially crafted file descriptor fd to the DRMVMWGBSURFACEREF or DRMVMWGBSURFACEREFEXT paths. This can lead to a dmabuf reference leak, causing resource exhaustion...
CVE-2026-80876
A flaw was found in the Linux kernel's ring-buffer component. When 8-byte alignment is enforced, the system incorrectly calculates the length of small events. This error causes these events to report a data length that is 4 bytes larger than their actual size. This discrepancy can lead to...
CVE-2026-80884
A flaw was found in the Linux kernel's NTB Non-Transparent Bridge module. This vulnerability arises from the incorrect handling of Direct Memory Access DMA addresses during memory deallocation. The DMA API requires that the dmafreeattrs function receives the exact dmahandle originally provided by...
CVE-2026-80873
A flaw was found in the Linux kernel's KVM Kernel-based Virtual Machine component on ARM64 systems. When a nested guest hypervisor L2 encounters a System Error SError exception, the ESREL2 register, which provides details about the exception, is not properly updated. This can cause the guest L2...
