kernel: ext4: fix deadlock due to mbcache entry corruption

A deadlock vulnerability was found in the ext4 filesystem in the Linux kernel. When manipulating extended attribute xattr blocks, a race condition in non-atomic bitfield updates can cause the mbcache entry state to become corrupted. This leads to an infinite loop in ext4xattrblockset where the co...

CVE-2021-46933 usb: gadget: f_fs: Clear ffs_eventfd in ffs_data_clear.

In the Linux kernel, the following vulnerability has been resolved: usb: gadget: ffs: Clear ffseventfd in ffsdataclear. ffsdataclear is indirectly called from both ffsfskillsb and ffsep0release, so it ends up being called twice when userland closes ep0 and then unmounts ffs. If userland provided ...

USN-3582-1 linux, linux-aws, linux-kvm, linux-raspi2, linux-snapdragon vulnerabilities

Mohamed Ghannam discovered that the IPv4 raw socket implementation in the Linux kernel contained a race condition leading to uninitialized pointer usage. A local attacker could use this to cause a denial of service or possibly execute arbitrary code. CVE-2017-17712 Laurent Guerby discovered that...

Linux kernel denial of service vulnerability (CNVD-2016-09487)

The Linux kernel is the kernel used by the operating system Linux, released by the Linux Foundation in the United States. A security vulnerability exists in the mbcache function during ext2 and ext4 filesystem realities in Linux kernel versions 4.5.7 and earlier, which stems from the program...
