USN-6573-1 linux-azure vulnerabilities

Lucas Leong discovered that the netfilter subsystem in the Linux kernel did not properly validate some attributes passed from userspace. A local attacker could use this to cause a denial of service system crash or possibly expose sensitive information kernel memory. CVE-2023-39189 Kyle Zeng...

CVE-2022-2588

It was discovered that the clsroute filter implementation in the Linux kernel would not remove an old filter from the hashtable before freeing it if its handle had the value 0...

CVE-2024-0193

A use-after-free flaw was found in the netfilter subsystem of the Linux kernel. If the catchall element is garbage-collected when the pipapo set is removed, the element can be deactivated twice. This can cause a use-after-free issue on an NFTCHAIN object or NFTOBJECT object, allowing a local...

kernel: IGB driver inadequate buffer size for frames larger than MTU

A flaw was found in igbconfigurerxring in drivers/net/ethernet/intel/igb/igbmain.c in the IGB driver in the Linux kernel. An overflow of the contents from a packet that is too large will overflow into the kernel's ring buffer, leading to a system integrity issue...

kernel: use-after-free in smb2_is_status_io_timeout()

A use-after-free flaw was found in smb2isstatusiotimeout in CIFS in the Linux Kernel. After CIFS transfers response data to a system call, there are still local variable points to the memory region, and if the system call frees it faster than CIFS uses it, CIFS will access a free memory region,...

The vulnerability of the Windows operating system’s kernel allows a perpetrator to gain unauthorized access to protected information.

The vulnerability of the Windows operating system’s kernel is related to insufficient protection of sensitive data. Exploiting this vulnerability can allow an attacker to gain unauthorized access to protected information...

PoC Code for Linux Kernel Privilege Escalation Flaw CVE-2023-259 Published https://securityonline.info/poc-code-for-linux-kernel-privilege-escalation-flaw-cve-2023-259-published/...

kernel: dm flakey: don't corrupt the zero page

A flaw was found in the Linux kernel's dm-flakey device mapper target. When the corrupt bio writes option is enabled, dm-flakey can corrupt the kernel's global zero page. Since the zero page is shared system-wide and used by glibc's calloc implementation via mmap, corrupting it causes userspace...

kernel: hid: Use After Free in asus_remove()

A use-after-free flaw was found in asuskbdbacklightset in drivers/hid/hid-asus.c in the Linux Kernel. This issue could allow an attacker to crash the system when plugging in or disconnecting a malicious USB device, which may lead to a kernel information leak problem...

kernel: Denial of service issue in az6027 driver in drivers/media/usb/dev-usb/az6027.c

A NULL pointer dereference flaw was found in the az6027 driver in drivers/media/usb/dev-usb/az6027.c in the Linux Kernel. The message from user space is not checked properly before transferring into the device. This flaw allows a local user to crash the system or potentially cause a denial of...

kernel: xfrm: NULL pointer dereference in xfrm_update_ae_params()

A flaw was found in the Linux kernel’s IP framework for transforming packets XFRM subsystem. This issue may allow a malicious user with CAPNETADMIN privileges to directly dereference a NULL pointer in xfrmupdateaeparams, leading to a possible kernel crash and denial of service...

kernel: Intel firmware update for insufficient granularity of access control in out-of-band management in some Intel Atom and Intel Xeon Scalable Processors

A flaw was found in the Linux kernel. A potential security vulnerability in some IntelR AtomR and IntelR XeonR Scalable Processors may allow privilege escalation. This flaw may allow a privileged user to enable privilege escalation via adjacent network access...

CVE-2023-42752

An integer overflow flaw was found in the Linux kernel. This issue leads to the kernel allocating skbsharedinfo in the userspace, which is exploitable in systems without SMAP protection since skbsharedinfo contains references to function pointers...

Kernel: ipv4: null pointer dereference in ipv4_send_dest_unreach()

kernel: ipvlan: out-of-bounds write caused by unclear skb->cb

A flaw was found in the IPVLAN network driver in the Linux kernel. This issue is caused by missing skb-cb initialization in ipoptionsecho and can lead to an out-of-bounds write stack overflow. This may allow a local user to cause a denial of service or potentially achieve local privilege escalati...

kernel: LoadPin bypass via dm-verity table reload

A flaw was found in the Linux kernel. Dm-verity is used for extending root-of-trust to root filesystems. LoadPin builds on this property to restrict module and firmware loads to just the trusted root filesystem. Device-mapper table reloads currently allow users with root privileges to switch out...

kernel: cls_flower: out-of-bounds write in fl_set_geneve_opt()

A flaw was found in the TC flower classifier clsflower in the Networking subsystem of the Linux kernel. This issue occurs when sending two TCAFLOWERKEYENCOPTSGENEVE packets with a total size of 252 bytes, which results in an out-of-bounds write when the third packet enters flsetgeneveopt,...

kernel: cls_flower: out-of-bounds write in fl_set_geneve_opt()

A flaw was found in the TC flower classifier clsflower in the Networking subsystem of the Linux kernel. This issue occurs when sending two TCAFLOWERKEYENCOPTSGENEVE packets with a total size of 252 bytes, which results in an out-of-bounds write when the third packet enters flsetgeneveopt,...
