The issue occurs when the socket is in TCP_SYN_SENT state and the reconnect path leaves rose->state as ROSE_STATE_1 with rose->neighbour set to NULL before the close path reaches rose_transmit_link().

612) Use-after-free (CVE-ID: CVE-2026-23458)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The issue can trigger a kernel warning when the directory link count wraps around to 0.

694) Improper resource shutdown or release (CVE-ID: CVE-2025-71287)

CWE-ID: CWE-404 - Improper Resource Shutdown or Release

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to improper resource shutdown or release in the mtk-smi larb probe logic when handling probe failures or driver unbind operations. A local user can trigger repeated probe deferral or unbind conditions to cause a denial of service.

695) Use-after-free (CVE-ID: CVE-2025-71274)

CWE-ID: CWE-416 - Use After Free

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to cause a denial of service.

The vulnerability exists due to a use-after-free in driver_override_show() when reading the driver_override string concurrently with updates. A local user can trigger concurrent read and write operations to cause a denial of service.

696) Loop with Unreachable Exit Condition ('Infinite Loop') (CVE-ID: CVE-2025-71267)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local attacker to cause a denial of service.

The vulnerability exists due to an infinite loop in the ntfs3 file system driver when processing a malformed NTFS image with a zero-sized ATTR_LIST attribute. A local attacker can mount a specially crafted NTFS image to cause a denial of service.

The attacker needs physical or local access to insert or mount the malicious NTFS image; no authentication beyond mounting the filesystem is required. The system becomes unresponsive during mount due to an infinite loop in kernel space.

697) Loop with Unreachable Exit Condition ('Infinite Loop') (CVE-ID: CVE-2025-71266)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local attacker to cause a denial of service.

The vulnerability exists due to improper input validation in the ntfs3 filesystem when handling a malformed dentry during lookup operations. A local attacker can provide a specially crafted NTFS-3 volume to cause a denial of service.

The attacker manipulates the HAS_SUB_NODE flag and VCN pointer in an INDEX_ENTRY, causing the indx_find() function to enter an infinite loop, repeatedly allocating memory until system resources are exhausted.

698) Loop with Unreachable Exit Condition ('Infinite Loop') (CVE-ID: CVE-2025-71265)

CWE-ID: CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local attacker to cause a denial of service.

The vulnerability exists due to an infinite loop in the ntfs3 file system's attr_load_runs_range function when processing inconsistent metadata. A local attacker can provide a malformed NTFS image to cause a denial of service.

The attacker-controlled NTFS image contains inconsistent metadata where an attribute header indicates an empty run list (evcn=-1 with svcn=0), but directory entries reference it as containing data. After a successful but empty run_unpack() call, the runs_tree remains uninitialized, causing subsequent run_lookup_entry() calls to fail and vcn to increment by zero, resulting in an infinite loop.

699) Insufficient logging (CVE-ID: CVE-2025-71239)

CWE-ID: CWE-778 - Insufficient Logging

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear

The vulnerability allows a local user to bypass audit logging.

The vulnerability exists due to improper audit event classification in the audit subsystem when handling the fchmodat2() system call. A local user can invoke fchmodat2() to change file attributes in a manner similar to chmod() or fchmodat(), which bypasses existing audit rules designed to monitor such operations.

The vulnerability specifically affects audit rules that monitor file attribute changes, allowing unauthorized attribute modifications to go unlogged. Authentication and local access are required to exploit this vulnerability.
