DEBIAN-CVE-2026-97026

Flatpak creates temporary child repository directories under the user cache with world-writable permissions 0777. On multi-user systems with a permissive umask, other local users could read or modify the temporary directory used while installing apps or runtimes, potentially causing installation...

DEBIAN-CVE-2026-97025

Flatpak writes the OCI repository authentication token with world-readable permissions 0644 in the system-helper's cache directory, allowing other local users on a multi-user system to read the token and impersonate the authenticated user against the OCI repository. Only OCI-based sources e.g. as...

CVE-2026-97026 Flatpak: flatpak: world-writable temporary child repositories in system-helper cache path

Flatpak creates temporary child repository directories under the user cache with world-writable permissions 0777. On multi-user systems with a permissive umask, other local users could read or modify the temporary directory used while installing apps or runtimes, potentially causing installation...

CVE-2026-98018

A flaw was found in the Linux kernel. A race condition in the Management Component Transport Protocol MCTP I3C driver occurs when device discovery releases a lock prematurely while a bus is simultaneously removed. A local user could exploit this synchronization flaw to access freed memory,...

CVE-2026-97534

A flaw was found in the Linux kernel's Flash-Friendly File System F2FS. When segment ranges are truncated, the file system fails to properly adjust the free section counter for sections that were already marked free, leading to an overestimation of available storage during background garbage...

CVE-2026-97532

A flaw was found in the Linux kernel's qla2xxx storage driver. When memory allocation fails during device initialization, the driver's error-handling routine fails to clear pointers to memory that has already been released. A local user capable of triggering device initialization failures can cau...

kernel: perf: Reject exited events as group leaders

A flaw was found in the Linux kernel's performance monitoring perf subsystem. This vulnerability allows a local attacker to trigger a use-after-free condition by improperly handling exited events as group leaders. Successful exploitation could lead to a system crash, resulting in a denial of...

kernel: perf/core: Detach event groups during remove_on_exec

A flaw was found in the Linux kernel's performance monitoring unit PMU subsystem. This vulnerability occurs when a performance event group leader is removed during process execution, but its associated events siblings remain active and linked to a stale list. This inconsistent state can lead to a...

CVE-2026-98012

A flaw was found in the Linux kernel's Stochastic Fairness Queueing SFQ network packet scheduling subsystem. A local attacker with network administration privileges, including within an unprivileged user namespace, can supply an improperly bounded quantum parameter alongside a crafted packet size...

CVE-2026-98011

A flaw was found in the Linux kernel's Heavy-Hitter Filter HHF network scheduler. A local attacker with network administration privileges, which can be acquired within an unprivileged user namespace, can cause a Denial of Service DoS. By setting an excessively small quantum value alongside a...

CVE-2026-98008

A flaw was found in the Linux kernel's Cadence MACB ethernet driver. A local user with administrative privileges could cause a denial of service DoS by triggering a driver unbind operation or an initialization failure on a device configured with a fixed-link connection. In this configuration, the...

CVE-2026-97529

A flaw was found in the Linux kernel's qla2xxx driver. The driver fails to validate the length of vendor-specific request buffers before reading command data, resulting in an out-of-bounds read from heap memory. A local user with administrative privileges can exploit this flaw by submitting a...

CVE-2026-98005

A flaw was found in the Linux kernel's EROFS Enhanced Read-Only File System component. Due to a missing delimiter between the domain identifier and fingerprint when generating cache keys for shared inodes, the resulting cache entries are ambiguous. A local user could exploit this ambiguity to cau...

kernel: perf: Reject exited events as group leaders

A flaw was found in the Linux kernel's performance monitoring perf subsystem. This vulnerability allows a local attacker to trigger a use-after-free condition by improperly handling exited events as group leaders. Successful exploitation could lead to a system crash, resulting in a denial of...

acl: Symlink traversal privilege escalation via libacl functions

A flaw was found in the acl package, specifically within its libacl pathname-based functions. A local attacker could exploit this vulnerability by using a symbolic link to replace a pathname component. This could allow the attacker to redirect access control list ACL read or write operations to...

CVE-2026-98003

A flaw was found in the Linux kernel's AMD Input-Output Memory Management Unit IOMMU driver. When the system resumes from sleep, the driver reallocates internal logging buffers without releasing previously allocated memory and performs memory requests in an invalid context. A local user with powe...
