Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in the Linux kernel that stems from the fact that a tasklet may hang on to another kernel, racing to remove irq...

kernel: memcg does not limit the number of POSIX file locks allowing memory exhaustion

A flaw was found in the filelockinit in fs/locks.c function in the Linux kernel. This issue can lead to host memory exhaustion due to memcg not limiting the number of Portable Operating System Interface POSIX file locks...

Design/Logic Flaw

In the Linux kernel, the following vulnerability has been resolved: btrfs: fix race between transaction aborts and fsyncs leading to use-after-free There is a race between a task aborting a transaction during a commit, a task doing an fsync and the transaction kthread, which leads to an...

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: 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,...

kernel: UAF during login when accessing the shost ipaddress

A use-after-free flaw was found in iscsiswtcpsessioncreate in drivers/scsi/iscsitcp.c in the SCSI sub-component in the Linux Kernel. This issue could allow an attacker to leak kernel internal information...

DEBIAN-CVE-2023-6531

A use-after-free flaw was found in the Linux Kernel due to a race problem in the unix garbage collector's deletion of SKB races with unixstreamreadgeneric on the socket that the SKB is queued on...

CVE-2024-0443

A flaw was found in the blkgs destruction path in block/blk-cgroup.c in the Linux kernel, leading to a cgroup blkio memory leakage problem. When a cgroup is being destroyed, cgrouprstatflush is only called at cssreleaseworkfn, which is called when the blkcg reference count reaches 0. This circula...

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...

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...

CVE-2023-39193

A flaw was found in the Netfilter subsystem in the Linux kernel. The sctpmtcheck did not validate the flagcount field. This flaw allows a local privileged CAPNETADMIN attacker to trigger an out-of-bounds read, leading to a crash or information disclosure...

CVE-2023-39194

A flaw was found in the XFRM subsystem in the Linux kernel. The specific flaw exists within the processing of state filters, which can result in a read past the end of an allocated buffer. This flaw allows a local privileged CAPNETADMIN attacker to trigger an out-of-bounds read, potentially leadi...
