2024-05-24 CVE-2021-47522 In the Linux kernel, the following vulnerability has been resolved: HID: bigbenff: prevent null pointer dereference When emulating the device through uhid, there is a chance we don't have output reports and so report_field is null. Linux_kernel 5.5
2024-05-24 CVE-2021-47525 In the Linux kernel, the following vulnerability has been resolved: serial: liteuart: fix use-after-free and memleak on unbind Deregister the port when unbinding the driver to prevent it from being used after releasing the driver data and leaking memory allocated by serial core. Linux_kernel 7.8
2024-05-24 CVE-2021-47526 In the Linux kernel, the following vulnerability has been resolved: serial: liteuart: Fix NULL pointer dereference in ->remove() drvdata has to be set in _probe() - otherwise platform_get_drvdata() causes null pointer dereference BUG in _remove(). Linux_kernel 5.5
2024-05-24 CVE-2021-47528 In the Linux kernel, the following vulnerability has been resolved: usb: cdnsp: Fix a NULL pointer dereference in cdnsp_endpoint_init() In cdnsp_endpoint_init(), cdnsp_ring_alloc() is assigned to pep->ring and there is a dereference of it in cdnsp_endpoint_init(), which could lead to a NULL pointer dereference on failure of cdnsp_ring_alloc(). Fix this bug by adding a check of pep->ring. This bug was found by a static analyzer. The analysis employs differential checking to identify... Linux_kernel 5.5
2024-05-24 CVE-2021-47529 In the Linux kernel, the following vulnerability has been resolved: iwlwifi: Fix memory leaks in error handling path Should an error occur (invalid TLV len or memory allocation failure), the memory already allocated in 'reduce_power_data' should be freed before returning, otherwise it is leaking. Linux_kernel 5.5
2024-05-24 CVE-2021-47537 In the Linux kernel, the following vulnerability has been resolved: octeontx2-af: Fix a memleak bug in rvu_mbox_init() In rvu_mbox_init(), mbox_regions is not freed or passed out under the switch-default region, which could lead to a memory leak. Fix this bug by changing 'return err' to 'goto free_regions'. This bug was found by a static analyzer. The analysis employs differential checking to identify inconsistent security operations (e.g., checks or kfrees) between two code paths and... Linux_kernel 5.5
2024-05-24 CVE-2021-47540 In the Linux kernel, the following vulnerability has been resolved: mt76: mt7915: fix NULL pointer dereference in mt7915_get_phy_mode Fix the following NULL pointer dereference in mt7915_get_phy_mode routine adding an ibss interface to the mt7915 driver. [ 101.137097] wlan0: Trigger new scan to find an IBSS to join [ 102.827039] wlan0: Creating new IBSS network, BSSID 26:a4:50:1a:6e:69 [ 103.064756] Unable to handle kernel NULL pointer dereference at virtual address 0000000000000000 [ ... Linux_kernel 5.5
2024-05-24 CVE-2021-47541 In the Linux kernel, the following vulnerability has been resolved: net/mlx4_en: Fix an use-after-free bug in mlx4_en_try_alloc_resources() In mlx4_en_try_alloc_resources(), mlx4_en_copy_priv() is called and tmp->tx_cq will be freed on the error path of mlx4_en_copy_priv(). After that mlx4_en_alloc_resources() is called and there is a dereference of &tmp->tx_cq[t][i] in mlx4_en_alloc_resources(), which could lead to a use after free problem on failure of mlx4_en_copy_priv(). Fix this bug... Linux_kernel 7.8
2024-05-24 CVE-2021-47542 In the Linux kernel, the following vulnerability has been resolved: net: qlogic: qlcnic: Fix a NULL pointer dereference in qlcnic_83xx_add_rings() In qlcnic_83xx_add_rings(), the indirect function of ahw->hw_ops->alloc_mbx_args will be called to allocate memory for cmd.req.arg, and there is a dereference of it in qlcnic_83xx_add_rings(), which could lead to a NULL pointer dereference on failure of the indirect function like qlcnic_83xx_alloc_mbx_args(). Fix this bug by adding a check of... Linux_kernel 5.5
2024-05-24 CVE-2021-47546 In the Linux kernel, the following vulnerability has been resolved: ipv6: fix memory leak in fib6_rule_suppress The kernel leaks memory when a `fib` rule is present in IPv6 nftables firewall rules and a suppress_prefix rule is present in the IPv6 routing rules (used by certain tools such as wg-quick). In such scenarios, every incoming packet will leak an allocation in `ip6_dst_cache` slab cache. After some hours of `bpftrace`-ing and source code reading, I tracked down the issue to...
