Linux vulnerabilities

In the Linux kernel, the following vulnerability has been resolved: NFSD: Protect against send buffer overflow in NFSv2 READ Since before the git era, NFSD has conserved the number of pages held by each nfsd thread by combining the RPC receive and send buffe…

In the Linux kernel, the following vulnerability has been resolved: NFSD: Protect against send buffer overflow in NFSv2 READDIR Restore the previous limit on the @count argument to prevent a buffer overflow attack.

In the Linux kernel, the following vulnerability has been resolved: Bluetooth: hci_event: Ignore multiple conn complete events When one of the three connection complete events is received multiple times for the same handle, the device is registered multiple …

In the Linux kernel, the following vulnerability has been resolved: inet: inet_defrag: prevent sk release while still in use ip_local_out() and other functions can pass skb->sk as function argument. If the skb is a fragment and reassembly happens before suc…

There is an infoleak vulnerability in the Linux kernel's net/bluetooth/l2cap_core.c's l2cap_parse_conf_req function which can be used to leak kernel pointers remotely. We recommend upgrading past commit  https://github.com/torvalds/linux/commit/b1a2cd50c0357f2…

usb_8dev_start_xmit in drivers/net/can/usb/usb_8dev.c in the Linux kernel through 5.17.1 has a double free.

In drivers/char/virtio_console.c in the Linux kernel before 5.13.4, data corruption or loss can be triggered by an untrusted device that supplies a buf->len value exceeding the buffer size. NOTE: the vendor indicates that the cited data corruption is not a vul…

In the Linux kernel before 2.6.34, a range check issue in drivers/gpu/drm/radeon/atombios.c could cause an off by one (buffer overflow) problem. NOTE: At least one Linux maintainer believes that this CVE is incorrectly assigned and should be rejected because t…

drivers/hid/hid-cp2112.c in the Linux kernel 4.9.x before 4.9.9 uses a spinlock without considering that sleeping is possible in a USB HID request callback, which allows local users to cause a denial of service (deadlock) via unspecified vectors.

The cookie feature in the packet action API implementation in net/sched/act_api.c in the Linux kernel 4.11.x through 4.11-rc7 mishandles the tb nlattr array, which allows local users to cause a denial of service (uninitialized memory access and refcount underf…

The proc_keys_show function in security/keys/proc.c in the Linux kernel through 4.8.2, when the GNU Compiler Collection (gcc) stack protector is enabled, uses an incorrect buffer size for certain timeout data, which allows local users to cause a denial of serv…

arch/arm/mm/dma-mapping.c in the Linux kernel before 3.13 on ARM platforms, as used in Android before 2016-08-05 on Nexus 5 and 7 (2013) devices, does not prevent executable DMA mappings, which might allow local users to gain privileges via a crafted applicati…

Untrusted search path vulnerability in the perf_config function in tools/perf/util/config.c in perf, as distributed in the Linux kernel before 3.1, allows local users to overwrite arbitrary files via a crafted config file in the current working directory.

Integer underflow in the irda_getsockopt function in net/irda/af_irda.c in the Linux kernel before 2.6.37 on platforms other than x86 allows local users to obtain potentially sensitive information from kernel heap memory via an IRLMP_ENUMDEVICES getsockopt cal…

Heap-based buffer overflow in the bcm_connect function in net/can/bcm.c (aka the Broadcast Manager) in the Controller Area Network (CAN) implementation in the Linux kernel before 2.6.36.2 on 64-bit platforms might allow local users to cause a denial of service…

Multiple integer overflows in the snd_ctl_new function in sound/core/control.c in the Linux kernel before 2.6.36-rc5-next-20100929 allow local users to cause a denial of service (heap memory corruption) or possibly have unspecified other impact via a crafted (…

Integer signedness error in the ax25_setsockopt function in net/ax25/af_ax25.c in the ax25 subsystem in the Linux kernel before 2.6.31.2 allows local users to cause a denial of service (OOPS) via a crafted optlen value in an SO_BINDTODEVICE operation.

The aio_setup_ring function in Linux kernel does not properly initialize a variable, which allows local users to cause a denial of service (crash) via an unspecified error path that causes an incorrect free operation.

The encrypted loop device in Linux kernel 2.4.10 and earlier does not authenticate the entity that is encrypting data, which allows local users to modify encrypted data without knowing the key.

In the Linux kernel, the following vulnerability has been resolved: iommu/amd: Avoid stack buffer overflow from kernel cmdline While the kernel command line is considered trusted in most environments, avoid writing 1 byte past the end of "acpiid" if the "str…

In the Linux kernel, the following vulnerability has been resolved: RDMA/bnxt_re: Fix max SGEs for the Work Request Gen P7 supports up to 13 SGEs for now. WQE software structure can hold only 6 now. Since the max send sge is reported as 13, the stack can giv…

mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c in the Linux kernel before 5.1.6 has some error-handling cases that did not free allocated hostcmd memory, aka CID-003b686ace82. This will cause a memory leak and denial of service.

The kvm_vm_ioctl_check_extension function in arch/powerpc/kvm/powerpc.c in the Linux kernel before 4.13.11 allows local users to cause a denial of service (NULL pointer dereference and system crash) via a KVM_CHECK_EXTENSION KVM_CAP_PPC_HTM ioctl call to /dev/…

The Human Interface Device (HID) subsystem in the Linux kernel through 3.11, when CONFIG_LOGITECH_FF, CONFIG_LOGIG940_FF, or CONFIG_LOGIWHEELS_FF is enabled, allows physically proximate attackers to cause a denial of service (heap-based out-of-bounds write) vi…

The isofs_export_encode_fh function in fs/isofs/export.c in the Linux kernel before 3.6 does not initialize a certain structure member, which allows local users to obtain sensitive information from kernel heap memory via a crafted application.
