CVE-2026-98695

A flaw was found in the Linux kernel's USB serial subsystem. A local user could cause a Denial of Service DoS due to a race condition between input/output control ioctl operations and device disconnection. If a USB serial device is disconnected during an active operation, the driver may attempt t...

kernel: ipv4: validate checksum_start before completing checksum

A flaw was found in the Linux kernel. A local attacker or untrusted guest virtual machine can exploit this vulnerability by transmitting network packets containing malformed checksum metadata into the IPv4 networking subsystem. This failure to validate checksum metadata can corrupt memory during...

An update for kernel is now available for Red Hat Enterprise Linux 9.6 Extended Update Support. Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, is available for...

CVE-2026-98694

A flaw was found in the Linux kernel's Thunderbolt driver. When a control channel request is canceled, a race condition can cause the request to be rescheduled after its memory has already been freed, resulting in a use-after-free vulnerability. A local attacker could exploit this flaw to cause a...

Security update for the Linux Kernel (Live Patch 52 for SUSE Linux Enterprise 15 SP4)

This update for the SUSE Linux Enterprise Kernel 5.14.21-150400.24.209 fixes various security issues: The following security issues were fixed: CVE-2026-53131: netfilter: require Ethernet MAC header before using ethhdr bsc1269775. CVE-2026-63794: KVM: SVM: Fix page overflow in sevdbgcrypt for...

CVE-2026-98693

A flaw was found in the Linux kernel's Thunderbolt driver. A physically proximate user or local attacker could trigger a Denial of Service DoS and crash the system by disconnecting a device or unbinding the driver while DisplayPort tunnel operations are still active. This issue occurs because the...

CVE-2026-98692

A flaw was found in the Linux kernel's Thunderbolt subsystem. DisplayPort DP tunnels activated without a required completion callback fail to release object references during tunnel setup, such as when restoring from system hibernation. A local user or repeated hibernation cycles can cause kernel...

CVE-2026-98691

A flaw was found in the Linux kernel's Thunderbolt subsystem. This vulnerability can lead to a Denial of Service DoS or system instability when a Thunderbolt device is disconnected or unbound. When a Thunderbolt domain is stopped, inactive DisplayPort DP tunnels are not properly torn down, allowi...

CVE-2026-98690

A flaw was found in the Linux kernel's Thunderbolt subsystem. This flaw allows a local user to cause a Denial of Service DoS by causing kernel cleanup operations to hang indefinitely. When a DisplayPort DP tunnel is disconnected before an internal read operation completes, the driver leaks an...

CVE-2026-98689

A flaw was found in the Linux kernel's Thunderbolt subsystem. A race condition occurs when DisplayPort DP read operations are canceled during system suspend or device disconnection, allowing work handlers to access tunnel structures that have already been torn down. A local attacker could trigger...

CVE-2026-98688

A flaw was found in the Linux kernel's Thunderbolt subsystem. A race condition during device removal operations can lead to a NULL pointer dereference. A local user could exploit this timing issue during device disconnection to trigger a kernel crash, resulting in a Denial of Service DoS...

CVE-2026-98687

A flaw was found in the Linux kernel's Thunderbolt driver. When processing property requests from peer devices, the driver fails to verify that the response data length does not exceed the allocated buffer size. A malicious peer can exploit this flaw by sending an oversized response packet,...

CVE-2026-98685

A flaw was found in the Linux kernel's SMB client. This vulnerability can lead to information disclosure when extending a file via a clone range operation. Because the client fails to discard cached memory pages that straddle the original end-of-file boundary, data previously written past the...

CVE-2026-98686

A flaw was found in the Linux kernel's SMB Server Message Block client. When extending a file using a zero-range operation, cached memory pages past the previous end-of-file boundary are not properly discarded. A local user can exploit this vulnerability to view stale or previously buffered data...

CVE-2026-98684

A flaw was found in the Linux kernel's Server Message Block SMB client. When performing file space allocation operations against certain remote servers, such as Windows servers, the client queries allocated file ranges before flushing recently written data. Because the remote server may report...

CVE-2026-98683

A flaw was found in the Linux kernel's SMB client. When zeroing a range within a file that does not reach the end of the file, dirty cached data is not flushed before the client requests the server to zero the region. A local user performing a zero-range operation could cause dirty cached pages t...

CVE-2026-98682

A flaw was found in the Linux kernel's Server Message Block SMB client subsystem. Due to improper synchronization during server-side file copy and clone operations, pending write operations are not drained before copying begins. A local user could exploit this timing issue during copy operations ...

CVE-2026-98681

A flaw was found in the Linux kernel's SMB Server Message Block client. Multiple internal file status flags shared the same memory byte without unified locking, creating a race condition during concurrent file operations. A local user performing simultaneous file operations could cause updates to...
