The even-denominator state appears in a 2D quasiparticle system, but researchers still can’t explain its origin.

Twelve new security flaws impacting various chipsets were disclosed in this month’s security advisory for Qualcomm’s devices, two of which have been given a critical severity rating. Two significant flaws in Qualcomm chipsets have been identified that might allow malicious payloads to installed remotely on the Android devices.

The first vulnerability, identified as CVE-2022–25748 (CVSS score 9.8), affects Qualcomm’s WLAN component and is described as a “Integer Overflow to Buffer Overflow during parsing GTK frames”. If exploited, this issue might result in memory corruption and remote code execution. This vulnerability impact all smart devices that use the Qualcomm Snapdragon APQ, CSRA, IPQ, MDM, MSM, QCA, WSA, WCN, WCD, SW, SM, SDX, SD, SA, QRB, QCS, QCN, and more series.

A security investigator has discovered three new code execution flaws in the Linux kernel that might be exploited by a local or external adversary to take control of the vulnerable computers and run arbitrary code. The roccat_report_event function in drivers/hid/hid-roccat.c has a use-after-free vulnerability identified as CVE-2022–41850 (CVSS score: 8.4). A local attacker might exploit this flaw to run malicious script on the system by submitting a report while copying a report->value. Patch has be released to addresses the Linux Kernel 5.19.12 vulnerability CVE-2022–41850.

The second flaw tracked as CVE-2022–41848 (CVSS score: 6.8), is also a use-after-free flaw due to a race condition between mgslpc_ioctl and mgslpc_detach in drivers/char/pcmcia/synclink_cs.c. By removing a PCMCIA device while calling ioctl, an attacker could exploit this vulnerability to execute arbitrary code on the system. The bug affects Linux Kernel 5.19.12 and was fixed via this patch.

In just 2 morrre, errr err, emmm, years?

They were supposed to be the future. But prominent detractors—including Anthony Levandowski, who pioneered the industry—are getting louder as the losses get bigger.

Summary: A newly discovered second stem cell population in the mouse brain is responsible for the production of new neurons in the olfactory bulb of adult mice.

In the brain of adult mammals, neural stem cells ensure that new nerve cells, i.e. neurons, are constantly formed. This process, known as adult neurogenesis, helps mice maintain their sense of smell.

Summary: Boosting omega-3 fatty acid intake helps to preserve brain health and improve cognition in middle age, a new study reports. For those with the Alzheimer’s associated APOE4 gene, omega-3 fatty acid intake was associated with greater hippocampal volume and less small vessel disease.
