CVE-2024-26947: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved: ARM: 9359/1: flush: check if the folio is reserved for no-mapping addresses Since commit a4d5613c4dc6 "arm: extend pfnvalid to take into account freed memory map alignment" changes the semantics of pfnvalid to check presence of t...

CVE-2024-27032: Loop with Unreachable Exit Condition

In the Linux kernel, the following vulnerability has been resolved: f2fs: fix to avoid potential panic during recovery During recovery, if FAULTBLOCK is on, it is possible that f2fsreservenewblock will return -ENOSPC during recovery, then it may trigger panic. Also, if fault injection rate is 1 a...

PT-2024-21626 · Linux · Linux Kernel

Name of the Vulnerable Software and Affected Versions: Linux kernel affected versions not specified Description: The issue arises from the function wq update node max active incorrectly calling cpumask test cpu with -1 CPU, leading to kernel panics on some architectures. This occurs when @off cpu...

kernel: ext4: fix delayed allocation bug in ext4_clu_mapped for bigalloc + inline

In the Linux kernel, the following vulnerability has been resolved: ext4: fix delayed allocation bug in ext4clumapped for bigalloc + inline When converting files with inline data to extents, delayed allocations made on a file system created with both the bigalloc and inline options can result in...

kernel: blk-cgroup: Reinit blkg_iostat_set after clearing in blkcg_reset_stats()

In the Linux kernel, the following vulnerability has been resolved: blk-cgroup: Reinit blkgiostatset after clearing in blkcgresetstats When blkgalloc is called to allocate a blkcggq structure with the associated blkgiostatset's, there are 2 fields within blkgiostatset that requires proper...

kernel: Linux kernel: Denial of Service in DRM scheduler due to improper work queue handling

A flaw was found in the Linux kernel's Direct Rendering Manager DRM scheduler. A local attacker with low privileges could exploit this vulnerability by triggering a GPU reset test. This improper handling of the scheduler work queue can lead to a kernel panic, which is a system crash, resulting in...

kernel: Linux kernel Bluetooth: Denial of Service via race condition in hidp_session_thread

A flaw was found in the Linux kernel's Bluetooth subsystem. A race condition in the hidpsessionthread can lead to a use-after-free vulnerability. This occurs when a timer is active while its deletion function is called, causing memory to be accessed after it has been freed. A local attacker could...

kernel: igc: Fix Kernel Panic during ndo_tx_timeout callback

A race condition was identified in the Intel “igc” network driver in the Linux kernel. Under specific heavy traffic and timing scenarios, such as when the transmit queue times out ndotxtimeout and the adapter reset path is invoked concurrently with device teardown or reinitialization, the driver...

kernel: ixgbe: Fix panic during XDP_TX with > 64 CPUs

A flaw was found in the Linux kernel's ixgbe network driver. On systems with more than 64 CPUs, XDPTX operations can cause a kernel panic due to an array-index-out-of-bounds access. The ixgbexdplockingkey variable can be incorrectly decremented to zero during ring reconfiguration, causing the...

kernel: Linux kernel: Out-of-bounds write in VXLAN due to incorrect nexthop hash size leading to denial of service

A flaw was found in the Linux kernel's Virtual Extensible LAN VXLAN implementation. An attacker with elevated privileges CAPNETADMIN can exploit this vulnerability by configuring the system to accept and forward VXLAN packets. The issue arises from an incorrect nexthop hash size, where a 32-bit...

kernel: USB: Gadget: core: Help prevent panic during UVC unconfigure

A deadlock flaw was found in the Linux kernel's USB Gadget subsystem in the driver unbind path. A local privileged user can trigger this issue by removing a UVC gadget driver from a gadget configuration, causing the unbind callback to call usbgadgetdeactivate while the caller holds the connectloc...

kernel: Linux kernel: Denial of Service in RDMA/bnxt_re driver due to race condition during QP destruction

A flaw was found in the Linux kernel's Remote Direct Memory Access RDMA bnxtre driver. A local user could exploit a race condition that occurs when a Queue Pair QP is destroyed, but completion queue CQ polling continues. This can lead to a kernel panic, resulting in a Denial of Service DoS on the...
