kernel: memory corruption in Voice over IP nf_conntrack_h323 module

An out-of-bounds memory write flaw was found in how the Linux kernel’s Voice Over IP H.323 connection tracking functionality handled connections on ipv6 port 1720. This flaw allows an unauthenticated remote user to crash the system, causing a denial of service. The highest threat from this...

kernel: out of bounds write in function i2c_smbus_xfer_emulated in drivers/i2c/i2c-core-smbus.c

An out of bounds OOB memory access flaw was found in i2csmbusxferemulated in drivers/i2c/i2c-core-smbus.c in I2C subsystem. A read request for length data-block0 greater than 'I2CSMBUSBLOCKMAX + 1' may cause underlying I2C driver write out of array's boundary. This could allow a local attacker wi...

kernel: memory leak in mwifiex_tm_cmd in drivers/net/wireless/marvell/mwifiex/cfg80211.c

A flaw was found in the Linux kernel's mwifiex driver implementation when connecting to other WiFi devices in "Test Mode." A kernel memory leak can occur if an error condition is met during the parameter negotiation. This issue can lead to a denial of service if multiple error conditions meeting...

kernel: memory leak in the nl80211_get_ftm_responder_stats() function in net/wireless/nl80211.c allows DoS

A flaw was found in the Linux kernel. The Wireless configuration API functionality mishandles resource cleanup in nl80211getftmresponderstats function. An attacker able to trigger the resource cleanup code path could use this flaw to crash the system. The highest threat from this vulnerability is...

kernel: A memory leak in the alloc_sgtable() function in drivers/net/wireless/intel/iwlwifi/fw/dbg.c allows for a DoS

A flaw was found in the Linux kernel. The Intel Wireless WiFi MVM Firmware driver mishandles resource cleanup during device coredump. An attacker able to trigger the device coredump and system-wide out of memory conditions at the same time could use this flaw to crash the system. The highest thre...

kernel: memory leak in the crypto_report() function in crypto/crypto_user_base.c allows for DoS

A flaw was found in the Linux kernel. The cryptoreport function mishandles resource cleanup on error. A local attacker able to induce the error conditions could use this flaw to crash the system. The highest threat from this vulnerability is to system availability...

A flaw was found in the Linux Kernel before 5.8-rc6 in the ZRAM kernel module where a user with a local account and the ability to read the /sys/class/zram-control/hot_add file can create ZRAM device nodes in the /dev/ directory. This read allocates kernel memory and is not accounted for a user that triggers the creation of that ZRAM device. With this vulnerability continually reading the device may consume a large amount of system memory and cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes possibly making the system inoperable.
