\"LINUX
\nThe staging driver fixes that were sent out this week ahead of the Linux 7.2-rc3 release is predominantly made up of hardening the Realtek RTL8723BS WiFi driver. In particular, a number of fixes for addressing out-of-bounds behavior when connecting to “bad” WiFi hosts.<\/p>\n

Alexandru Hossu has been working on addressing a number of out-of-bounds “OOB” memory access conditions that could occur when the driver is iterating on attacker-controlled data provided from over-the-air frames. The driver was not properly validating the header or payload that could lead to a number of OOB reads\/writes if connecting to a malicious WiFi access point. <\/p>\n

These patches are set to be merged today ahead of the Linux 7.2-rc3 kernel release. These security fixes are also set to be back-ported to the existing Linux stable kernel versions too. These security shortcomings around over-the-air WiFi data handling have existed since the rtl8723bs driver was added to the Linux kernel’s staging area back in 2017. <\/p>\n

\"Realtek<\/p>\n

Since the staging admission nearly a decade ago, the Realtek RTL8723BS has continued seeing much driver cleaning with nearly ever kernel cycle with it proving to be a “beast of a driver” in code complexity<\/a>. The Realtek RTL8723BS is an 802.11 b\/g\/n SDIO WiFi chipset with Bluetooth 4.0 support and over the years has been found in many different devices. <\/p>\n

These out-of-bounds fixes when dealing with nefarious WiFi hosts is the main set of changes with this week’s staging fixes<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"The staging driver fixes that were sent out this week ahead of the Linux 7.2-rc3 release is predominantly…\n","protected":false},"author":2,"featured_media":545773,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[7165,61,60,7164,7162,7161,7168,7166,7163,7167,7160,7171,80,7169,7170],"class_list":["post-545772","post","type-post","status-publish","format-standard","has-post-thumbnail","category-technology","tag-desktop-linux","tag-ie","tag-ireland","tag-linux-benchmarking","tag-linux-hardware-benchmarks","tag-linux-hardware-reviews","tag-linux-how-to","tag-linux-performance","tag-linux-server-benchmarks","tag-open-source-graphics","tag-phoronix","tag-phoronix-test-suite","tag-technology","tag-ubuntu-benchmarks","tag-ubuntu-hardware"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/545772","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/comments?post=545772"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/posts\/545772\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media\/545773"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/media?parent=545772"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/categories?post=545772"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ie\/wp-json\/wp\/v2\/tags?post=545772"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
