Astra Linux – Vulnerability in Linux 5.10, Linux, Linux 5.15

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: do not trust the firmware’s nChannels value. If the firmware sends us a corrupted MCC response where nChannels is much larger than what the command response can handle, we might copy too much uninitialized...

kernel: wifi: mac80211: Set n_channels after allocating struct cfg80211_scan_request

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: Set nchannels after allocating struct cfg80211scanrequest Make sure that nchannels is set after allocating the struct cfg80211registereddevice::intscanreq member. Seen with syzkaller: UBSAN:...

CVE-2023-53589

CVE-2023-53589 affects the Linux kernel’s wireless stack: the iwlwifi mvm driver may mishandle a corrupted MCC response from firmware if n_channels is larger than the command response can contain. This can lead to copying excessive (uninitialized) memory and, in extreme cases, a crash due to memo...

CVE-2023-53589 wifi: iwlwifi: mvm: don't trust firmware n_channels

In the Linux kernel, the following vulnerability has been resolved: wifi: iwlwifi: mvm: don't trust firmware nchannels If the firmware sends us a corrupted MCC response with nchannels much larger than the command response can be, we might copy far too much uninitialized memory and even crash if t...

In the Linux kernel, the following vulnerability has been resolved: wifi: mac80211: Set nchannels after allocating struct cfg80211scanrequest Make sure that nchannels is set after allocating the struct cfg80211registereddevice::intscanreq member. Seen with syzkaller: UBSAN:...

Linux Kernel Security Vulnerabilities

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. A security vulnerability exists in Linux kernel that stems from not setting nchannels correctly, which could lead to out-of-bounds access to arrays...

In the Linux kernel, the following vulnerabilities have been resolved: wifi: mac80211: Set nchannels after allocating the structcfg80211scanrequest structure. Make sure that nchannels is set after allocating the structcfg80211registereddevice::intscanreq member. This issue was identified using...

SUSE CVE-2024-53189

In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: fix bounds checker error in nl80211parseschedscan The channels array in the cfg80211scanrequest has a countedby attribute attached to it, which points to the nchannels variable. This attribute is used in bounds...

DEBIAN-CVE-2024-47607

GStreamer is a library for constructing graphs of media-handling components. stack-buffer overflow has been detected in the gstopusdecparseheader function within gstopusdec.c'. The pos array is a stack-allocated buffer of size 64. If nchannels exceeds 64, the for loop will write beyond the...

SUSE CVE-2024-38562

In the Linux kernel, the following vulnerability has been resolved: wifi: nl80211: Avoid address calculations via out of bounds array indexing Before request-channels can be used, request-nchannels must be set. Additionally, address calculations for memory after the "channels" array need to be...
