CVE-2024-26947 ARM: 9359/1: flush: check if the folio is reserved for no-mapping addresses

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...

kernel: refscale: Fix uninitalized use of wait_queue_head_t

A use of uninitialized data was found in the refscale test module. The waitqueueheadt is used before being initialized, causing a race condition that can crash the kernel during testing...

kernel: bpf: Disable preemption in bpf_event_output

A race condition was found in the BPF event output mechanism. When preemption is enabled during bpfeventoutput, two tasks can access the same perfsampledata buffer concurrently, leading to data corruption and kernel crashes...

kernel: hwmon: (coretemp) Simplify platform device handling

A NULL pointer dereference flaw was found in the Linux kernel's coretemp hardware monitoring driver in the platform device handling logic. A local privileged user who disables driversautoprobe for the platform bus can trigger this issue by initiating CPU hotplug operations, causing the driver to...

kernel: net/mlx5e: Check for NOT_READY flag state after locking

A race condition was found in the Linux kernel Mellanox mlx5 network driver's traffic control offload flow management. A local user with privileges to configure traffic control flower filters can trigger concurrent flow deletion operations where the NOTREADY flag is checked before acquiring the...

kernel: ext4: fix BUG in ext4_mb_new_inode_pa() due to overflow

An integer overflow flaw was found in the Linux kernel's ext4 filesystem. In ext4mbnewinodepa, when calculating the end position of ext4freeextent, the computation can overflow ext4lblkt uint32 to zero. This occurs with large logical block numbers near UINTMAX, causing a BUGON assertion failure a...

kernel: wifi: ath11k: Add missing hw_ops->get_ring_selector() for IPQ5018

A flaw was discovered in the ath11k wireless driver in the Linux kernel where the hardware operations structure for the IPQ5018 platform did not include a hwops-getringselector callback. When network traffic is being sent after clients have connected, this missing function pointer may be...

kernel: opp: Fix use-after-free in lazy_opp_tables after probe deferral

A flaw was found in the Linux kernel's OPP Operating Performance Points subsystem. When probe deferral occurs due to unavailable interconnect paths, the OPP table is freed but not removed from the global lazyopptables list. This leads to a use-after-free when the required-opps provider is later...

kernel: Linux kernel (CIFS): Use-after-free vulnerability allows data integrity compromise and denial of service

A flaw was found in the Linux kernel's Common Internet File System CIFS component. This use-after-free vulnerability occurs due to improper handling of server hostname information during connection re-establishment. An attacker on an adjacent network could exploit this, potentially leading to a...

kernel: ext4: fix bug_on in __es_tree_search caused by bad boot loader inode

A flaw was identified in the ext4 filesystem implementation in the Linux kernel where a malformed or improperly initialized boot loader inode could trigger a BUGON condition inside the estreesearch function. This occurs when the inode’s mode imode is an unexpected type and the code does not...

kernel: KVM: SVM: Get source vCPUs from source VM for SEV-ES intrahost migration

A flaw was found in the Linux kernel's KVM SVM implementation for AMD SEV-ES. During intrahost VM migration, KVM incorrectly retrieves source vCPUs from the destination VM instead of the source VM. This causes the VMSA Virtual Machine Save Area pointer to remain NULL, leading to a host kernel cra...

kernel: drm/amdgpu: Fix sdma v4 sw fini error

An invalid pointer dereference flaw was found in the Linux kernel AMD GPU SDMA v4 driver's cleanup code. On systems with SDMA 4.2.2 hardware, driver unload or system shutdown triggers the sdmav40swfini cleanup path, which attempts to release firmware using an uninitialized or corrupted pointer,...

kernel: OPP: Fix potential null ptr dereference in dev_pm_opp_get_required_pstate()

A NULL pointer dereference flaw was found in the Linux kernel's OPP Operating Performance Points framework in the power state retrieval logic. A local user can trigger this issue by invoking power management operations when the OPP pointer is dereferenced to cache the opptable before checking...

kernel: mm: multi-gen LRU: fix crash during cgroup migration

In the Linux kernel, the following vulnerability has been resolved: mm: multi-gen LRU: fix crash during cgroup migration lrugenmigratemm assumes lrugenaddmm runs prior to itself. This isn't true for the following scenario: CPU 1 CPU 2 clone cgroupcanfork cgroupprocswrite cgrouppostfork tasklock...

kernel: net/core: kernel crash in ETH_P_1588 flow dissector

A flaw was found in the ETHP1588 flow dissector in the Linux Kernel, which can lead to a kernel crash...

kernel: netfilter: race condition between IPSET_CMD_ADD and IPSET_CMD_SWAP

A flaw was found in the Netfilter subsystem of the Linux kernel. A race condition between IPSETCMDADD and IPSETCMDSWAP can lead to a kernel panic due to the invocation of ipsetput on a wrong set. This issue may allow a local user to crash the system...

kernel: Bluetooth: hci_conn: Fix crash on hci_create_cis_sync

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hciconn: Fix crash on hcicreatecissync When attempting to connect multiple ISO sockets without using DEFERSETUP may result in the following crash: BUG: KASAN: null-ptr-deref in hcicreatecissync+0x18b/0x2b0 Read of size...

kernel: ext4: set goal start correctly in ext4_mb_normalize_request

A flaw was found in the Linux kernel's ext4 filesystem block allocator. In ext4mbnormalizerequest, the goal start was being set incorrectly acfex instead of acgex, and boundary validation was missing. Without proper range checking, an underflow in ar-pright - size could pass an invalid value to...
