CVE-2026-86247

A flaw was found in Apache Tomcat Native. A race condition within a thread allows client certificate verification requirements to be down-graded for certain configurations. This could enable an attacker to bypass stricter authentication requirements, potentially leading to unauthorized access or...

CVE-2026-97565

A flaw was found in the Linux kernel's SMB Server Message Block client. When communicating with a malicious or compromised server, the client fails to verify that an incoming read response meets the expected minimum header size before accessing header fields. A malicious server can send a truncat...

CVE-2026-97564

A flaw was found in the Linux kernel's SMB Server Message Block client. This vulnerability allows a local user to achieve privilege escalation due to missing validation on identity mapping key descriptions. Because the kernel does not verify that identity mapping requests originate internally, a...

CVE-2026-97563

A flaw was found in the Linux kernel's Server Message Block SMB client. When processing SMB version 1 responses, the read handler does not properly validate the data offset value sent by the server. A malicious or compromised SMB server can exploit this flaw by returning a crafted response with a...

CVE-2026-97562

A flaw was found in the Linux kernel's SMB Server Message Block client. A race condition occurs when a Distributed File System DFS automount expires while the client processes active filesystem references, resulting in a use-after-free memory flaw. A local user could exploit this timing issue...

CVE-2026-97561

A flaw was found in the Linux kernel's Server Message Block SMB client. When an administrator mounts a remote share with options configured to force specific local user and group ownership, the client fails to enforce these restrictions and instead accepts ownership values provided by the remote...

CVE-2026-97560

A flaw was found in the Linux kernel's SMB Server Message Block client. When parsing a share-root relative native symbolic link, an incorrect length calculation causes the client to read past the end of the allocated buffer in the smb2parsenativesymlink function. A malicious server or attacker...

CVE-2026-97559

A flaw was found in the Linux kernel's SMB client. An integer overflow during Discretionary Access Control List DACL reconstruction can allow a local user to corrupt file access permissions sent to a remote server. When processing file permission or ownership updates with numerous access control...

CVE-2026-97558

A flaw was found in the Linux kernel's SMB Server Message Block client subsystem, which can lead to a Denial of Service DoS. Due to a timing issue during deferred file close operations, the kernel fails to properly release an internal file reference count when background cleanup work is already...

CVE-2026-97557

A flaw was found in the Linux kernel's Server Message Block SMB client. This flaw allows a remote or slow-responding SMB server to cause a Denial of Service DoS through a kernel crash. When handling opportunistic lock oplock break requests, the client can leak file reference counters if a new...

CVE-2026-97556

A flaw was found in the Linux kernel's SMB client. This vulnerability can lead to a denial of service DoS on systems using multi-user CIFS mount configurations. When processing an opportunistic lock oplock break, an error during tree link lookup prevents the client from releasing an acquired file...

CVE-2026-97555

A flaw was found in the Linux kernel's SMB client. When rewriting a Discretionary Access Control List DACL during file ownership updates, the kernel allocates memory based on the original identifier lengths rather than accounting for larger replacement Security Identifiers SIDs. A local user can...

CVE-2026-97554

A flaw was found in the Linux kernel's Server Message Block SMB client. When handling malformed directory entries with invalid security identifiers, the client fails to verify whether data parsing succeeded before processing file attributes. A malicious or compromised server could exploit this...
