The remote Ubuntu 20.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-7517-1 advisory. Several security issues were discovered in the Linux kernel. An attacker could possibly use these to compromise the system. This update corrects flaws in...

CVE-2025-47287

Tornado is a Python web framework and asynchronous networking library. When Tornado's multipart/form-data parser encounters certain errors, it logs a warning but continues trying to parse the remainder of the data. This allows remote attackers to generate an extremely high volume of logs,...

kernel: netfilter: ipset: add missing range check in bitmap_ip_uadt

In the Linux kernel, the following vulnerability has been resolved: netfilter: ipset: add missing range check in bitmapipuadt When tbIPSETATTRIPTO is not present but tbIPSETATTRCIDR exists, the values of ip and ipto are slightly swapped. Therefore, the range check for ip should be done later, but...

PT-2025-27717

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: A vulnerability in the Linux kernel has been resolved, related to the coresight subsystem. The issue allowed for a potential use-after-free UAF scenario when deactivating an active...

PT-2025-29029

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The Linux kernel contains an issue within the drm/xe/vm subsystem. A flaw exists in the xe vm close and put function where xe svm fini can be called prematurely during virtual machine...

CVE-2025-30388

Heap-based buffer overflow in Windows Win32K - GRFX allows an unauthorized attacker to execute code locally...

kernel: Bluetooth: hci_conn: Use disable_delayed_work_sync

A flaw was found in the Bluetooth subsystem of the Linux kernel, in the handling of delayed work within the hciconn Host Controller Interface connection structure. The kernel used canceldelayedworksync when shutting down a connection, which cancels ongoing work but allows rescheduling. This could...

kernel: net: usb: lan78xx: Fix double free issue with interrupt buffer allocation

A double free vulnerability was found in the Linux kernel. In lan78xxprobe, the buf buffer is freed twice: once implicitly through usbfreeurbdev-urbintr with the URBFREEBUFFER flag and again explicitly by kfreebuf, resulting in loss of availability of the system...

kernel: md/raid10: fix null ptr dereference in raid10_size()

A flaw was found in the Linux kernel's md/raid10 component. A local attacker could trigger a null pointer dereference in the raid10size function. This occurs when an internal function returns zero, but a critical data structure remains uninitialized, leading to a system crash. This vulnerability...

kernel: padata: use integer wrap around to prevent deadlock on seq_nr overflow

A flaw was found in the padata parallel algorithm data subsystem in the Linux kernel. An integer overflow can be triggered when processing more than 2^32 4GiB padata objects, causing a deadlock in the serialization process, potentially resulting in a denial of service...

kernel: tty: n_gsm: Fix use-after-free in gsm_cleanup_mux

A user after free vulnerability exists in the linux kernel such that when gsmcleanupmux is called,the gsmmsg on the txctrllist is not freed,resulting in loss of availability of the system...

kernel: wifi: mac80211: use two-phase skb reclamation in ieee80211_do_stop()

A flaw was found in the Linux kernel's mac80211 wireless subsystem. A local attacker with low privileges could trigger a condition where the system attempts to transmit data with interrupts disabled during the ieee80211dostop function. This incorrect handling of network packet buffers SKBs can le...

kernel: block: fix deadlock between sd_remove & sd_release

In the Linux kernel, the following vulnerability has been resolved: block: fix deadlock between sdremove & sdrelease Our test report the following hung task: 2538.459400 INFO: task "kworker/0:0":7 blocked for more than 188 seconds. 2538.459427 Call trace: 2538.459430 switchto+0x174/0x338...

kernel: Bluetooth: Fix memory leak in hci_req_sync_complete()

This CVE identifies a memory leak in the Linux kernel's Bluetooth subsystem, specifically within the hcireqsynccomplete function. The issue arises because the function fails to release the previous synchronization request state before assigning a new one, leading to increased memory usage over...

kernel: pipe: wakeup wr_wait after setting max_usage

CVE-2023-52672 is a vulnerability in the Linux kernel's pipe subsystem caused by a regression in how pipes are resized. When a pipe is full and resized, incorrect handling of wakeups for writers can lead to deadlocks or system lockups. This issue has been resolved by ensuring that the pipe's usag...

kernel: scsi: ufs: core: Fix handling of lrbp->cmd

In the Linux kernel, the following vulnerability has been resolved: scsi: ufs: core: Fix handling of lrbp-cmd ufshcdqueuecommand may be called two times in a row for a SCSI command before it is completed. Hence make the following changes: - In the functions that submit a command, do not check the...

USN-7506-4 linux-lts-xenial vulnerabilities

Demi Marie Obenour and Simon Gaiser discovered that several Xen para- virtualization device frontends did not properly restrict the access rights of device backends. An attacker could possibly use a malicious Xen backend to gain access to memory pages of a guest VM or cause a denial of service in...

PT-2025-54889

This update for freetype2 fixes the following issues: Update to 2.13.2: Some fields in the FT Outline structure have been changed from signed to unsigned type, which better reflects the actual usage. It is also an additional means to protect against malformed input. Rare double-free crashes in th...

USN-7506-3 linux-fips vulnerabilities

Demi Marie Obenour and Simon Gaiser discovered that several Xen para- virtualization device frontends did not properly restrict the access rights of device backends.
