kernel: drm/amdgpu: Refactor amdgpu_gem_va_ioctl for Handling Last Fence Update and Timeline Management v4

A flaw was found in the Linux kernel's AMD GPU amdgpu driver. Incorrect management of graphics memory dmafence references within the amdgpugemvaioctl function can lead to a reference count underflow and a use-after-after-free condition. A local attacker could exploit this vulnerability to trigger...

CVE-2026-72463

A flaw was found in the Linux kernel's xfrm IP eXtensible FRamework for IPsec subsystem. This vulnerability occurs during asynchronous resumption where the xfrmrcvcb function can modify a network device without properly managing its reference count. This improper handling leads to a use-after-fre...

CVE-2026-74405

A flaw was found in the Linux kernel. A race condition exists within the Optimized Power Performance OPP subsystem, where a newly added OPP object is exposed before its internal reference count is fully initialized. A concurrent operation can then increment this uninitialized reference count,...

CVE-2026-72461

A flaw was found in the AppArmor security module of the Linux kernel. This vulnerability, a reference count leak when updating the skctx, occurs because a reference is unconditionally put by the caller even when it has been transferred. A local attacker could exploit this flaw to cause a denial o...

CVE-2026-49419

When the JAILATDESC flag is specified, kernjailset and kernjailget released the reference to the caller's current prison before looking up the jail descriptor. If the descriptor lookup failed, error-handling paths released the same reference a second time. An unprivileged local user can trigger a...

CVE-2026-72307

A flaw was found in the Linux kernel's mlxsw driver. When the mlxswspvrslpmtreereplace function encounters an error during Virtual Router VR replacement operations, its rollback mechanism fails to correctly release resources. This leads to a reference count leak, where system resources are not...

CVE-2026-72040

A flaw was found in the Linux kernel's Intelligent Platform Management Interface IPMI subsystem. When a caller provides a message to the iipmirequest function, a reference count is incremented. However, if an error occurs during this process, the reference count is not properly decremented,...

CVE-2026-72308

A flaw was found in the mlxsw driver of the Linux kernel. This vulnerability occurs when the mlxswspportlagjoin function fails to properly release a network resource reference, leading to a reference count leak. Over time, this leak could exhaust system resources, potentially resulting in a denia...

CVE-2026-49419

When the JAILATDESC flag is specified, kernjailset and kernjailget released the reference to the caller's current prison before looking up the jail descriptor. If the descriptor lookup failed, error-handling paths released the same reference a second time. An unprivileged local user can trigger a...

CVE-2026-49419 Jail reference count underflow

When the JAILATDESC flag is specified, kernjailset and kernjailget released the reference to the caller's current prison before looking up the jail descriptor. If the descriptor lookup failed, error-handling paths released the same reference a second time. An unprivileged local user can trigger a...

CVE-2026-72218

A flaw was found in the Linux kernel's lockd component. A reference count leak occurs when nlmdofopen fails on a cached file path. This prevents the file's reference count from returning to zero, causing a resource leak. Over time, this can lead to resource exhaustion and a Denial of Service DoS...

CVE-2026-72082

A flaw was found in the Linux kernel's SCSI Small Computer System Interface elx: efct module. This vulnerability occurs when an I/O abort operation fails to properly release a resource reference. This can lead to a permanent resource leak, which prevents subsequent attempts to abort the same I/O...

CVE-2026-72042

A flaw was found in the Linux kernel's Intelligent Platform Management Interface IPMI subsystem. An issue in the event delivery mechanism, specifically a reference count underflow, can lead to a use-after-free vulnerability. This occurs when a user's reference count is prematurely decremented...

SUSE CVE-2026-74528

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hcisync: hold conn in hcipastsync callback Avoids giving freed pointers to hciconnvalid, which kmalloc may have reused. Hold refcount to avoid that...

CVE-2026-74568

In the Linux kernel, the following vulnerability has been resolved: KVM: arm64: vgic: Fix race between LPI release and re-registration Fix a potential race between decrementing an LPI's reference count and evicting that structure from the LPI xarray. LPI structures are maintained in the VGIC LPI...

CVE-2026-74531

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hciconn: hold conn reference in abortconnsync There is theoretical UAF if the conn is freed while the hcisync task is running. Hold refcount to avoid that...
