The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - accel/amxdna: Fix page-insertion errors in amdxdnainsertpages Two error paths in amdxdnainsertpages called vma-vmops-closevma before returning an error code to...

PT-2026-79726

Name of the Vulnerable Software and Affected Versions Linux kernel affected versions not specified Description An issue exists in the amdxdna insert pages function where two error paths incorrectly call vma-vm ops-closevma before returning an error code. This occurs because amdxdna gem obj mmap...

AZL-97001 CVE-2026-74581 affecting package kernel for versions less than 6.6.152.1-1

In the Linux kernel, the following vulnerability has been resolved: net: ipv6: clear suppressed fib6 rule result fib6rulesuppress drops a suppressed route with ip6rtputflags, but leaves res-rt6 pointing at the released rt6info. If no later rule supplies a replacement, fib6rulelookup still sees...

CVE-2026-74288

A flaw was found in the Linux kernel's networking subsystem. During the process of dumping network routing rules fibrulesdump, a race condition could occur where a 'dying' rule one being deallocated is incorrectly accessed. This could lead to a reference count error, potentially causing a system...

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

The FreeBSD operating system (versions 15.0 and later ) is vulnerable to a prison reference count underflow in the kern_jail_set() and kern_jail_get() functions. When the JAIL_AT_DESC flag is used, the system incorrectly releases a reference to the caller's current prison before searching for the...
